-# Runs the CURRENT test suite with two different rsync binaries: the freshly
-# built ./rsync as the client/driver, and a committed OLD static binary
-# (old_versions/rsync_<ver>) as the daemon / remote-shell peer. This exercises
-# real version mixing over the wire -- more convincing than --protocol forcing,
-# which only makes the current binary speak an old protocol.
-#
-# Direction is fixed: the current binary always drives (only it understands the
-# new test scripts); the old binary is only ever the server/daemon side. The
-# reverse (old client driving new scripts) is not possible -- but one test,
-# reverse-daemon-delta, swaps the roles internally (current build as the daemon,
-# old binary as the client) to cover the backward-compat direction: a current
-# daemon serving the installed base of old clients.
-#
-# The per-version manifest testsuite/expect/rsync_<ver>.expect lists exactly
-# which tests run and each one's expected outcome (pass/skip/fail/xfail), so an
-# old peer's known feature gaps are recorded rather than treated as breakage.
-#
-# All peers run in a SINGLE job (looped, not a matrix) so the PR shows one check
-# line rather than one per version. Each peer/transport is a foldable ::group::
-# in the log, and a failure annotates which peer/transport broke.

-## Changes in this version:
-
-### SECURITY FIXES:
-
-Six CVEs are fixed in this release.  All six are assigned by
-VulnCheck as CNA.  Affected versions are 3.4.2 and earlier in every
-case.  Three of the six (CVE-2026-29518, CVE-2026-43617,
-CVE-2026-43619) require non-default daemon configuration to reach:
-the first and third need `use chroot = no` for a module, the second
-needs `daemon chroot = ...` set in rsyncd.conf.  Two (CVE-2026-43618,
-CVE-2026-43620) are reachable from a normal pull or a normal
-authenticated daemon connection.  The sixth (CVE-2026-45232) is
-reachable only when `RSYNC_PROXY` is set and the proxy (or a MITM)
-returns a pathological response.  Many thanks to the external
-researchers who reported these issues.
-
-- CVE-2026-29518 (CVSS v4.0 7.3, HIGH): TOCTOU symlink race condition
-  allowing local privilege escalation in daemon mode without chroot.
-  An rsync daemon configured with "use chroot = no" was exposed to a
-  time-of-check / time-of-use race on parent path components: a local
-  attacker with write access to a module could replace a parent
-  directory component with a symlink between the receiver's check and
-  its open(), redirecting reads (basis-file disclosure) and writes
-  (file overwrite) outside the module.  Default "use chroot = yes" is
-  not exposed.  `secure_relative_open()` (added in 3.4.0 for
-  CVE-2024-12086) was previously unused in the daemon-no-chroot
-  case; the fix enables it there and reroutes the sender's
-  read-path opens through it.  Reported by Nullx3D (Batuhan Sancak),
-  Damien Neil and Michael Stapelberg.
-
-- CVE-2026-43617 (CVSS v3.1 4.8, MEDIUM): Hostname/ACL bypass on an
-  rsync daemon configured with `daemon chroot = /X` in rsyncd.conf
-  when the chroot tree lacks DNS resolution support.  The
-  reverse-DNS lookup of the connecting client was performed *after*
-  the daemon chroot had been entered; if /X did not contain the
-  libc resolver fixtures (`/etc/resolv.conf`, `/etc/nsswitch.conf`,
-  `/etc/hosts`, NSS service modules) the lookup failed and the
-  connecting hostname was set to "UNKNOWN", causing hostname-based
-  deny rules to silently fail open.  IP-based ACLs are unaffected.
-  The per-module `use chroot` setting is unrelated to this issue.
-  The fix performs the lookup before entering the daemon chroot.
-  Reported by MegaManSec.
-
-- CVE-2026-43618 (CVSS v3.1 8.1, HIGH): Integer overflow in the
-  compressed-token decoder enabling remote memory disclosure to an
-  authenticated daemon peer.  The receiver accumulated a 32-bit
-  signed counter without overflow checking; a malicious sender could
-  trigger an overflow that, with careful manipulation, leaked process
-  memory contents to the attacker -- environment variables,
-  passwords, heap and library pointers -- significantly weakening
-  ASLR.  The fix bounds the counter and adds wire-input validation in
-  several adjacent places (defence-in-depth).  Workaround for older
-  releases: `refuse options = compress` in rsyncd.conf.  Reported by
-  Omar Elsayed.
-
-- CVE-2026-43619 (CVSS v3.1 6.3, MEDIUM): Symlink races on path-based
-  system calls in "use chroot = no" daemon mode (generalisation of
-  CVE-2026-29518).  Earlier fixes for symlink races on the receiver's
-  open() call missed the same race class on every other path-based
-  system call: chmod, lchown, utimes, rename, unlink, mkdir, symlink,
-  mknod, link, rmdir and lstat.  The fix routes each affected
-  path-based syscall through a parent dirfd opened under
-  RESOLVE_BENEATH-equivalent kernel-enforced confinement (openat2 on
-  Linux 5.6+, O_RESOLVE_BENEATH on FreeBSD 13+ and macOS 15+,
-  per-component O_NOFOLLOW walk elsewhere).  Default "use chroot =
-  yes" is not exposed.  Reported by Andrew Tridgell as a follow-on
-  audit of CVE-2026-29518.
-
-- CVE-2026-43620 (CVSS v3.1 6.5, MEDIUM): Out-of-bounds read in the
-  receiver's recv_files() enabling remote denial-of-service of any
-  client pulling from a malicious server (incomplete fix of commit
-  797e17f).  The earlier parent_ndx<0 guard added to send_files() was
-  not applied to the visually-identical block in recv_files().  A
-  malicious rsync server can drive any connecting client into a
-  deterministic SIGSEGV by setting CF_INC_RECURSE in the
-  compatibility flags and sending a crafted file list and transfer
-  record.  inc_recurse is the protocol-30+ default, so no special
-  options are required on the victim.  Workaround for older
-  releases: `--no-inc-recursive` on the client.  Reported by Pratham
-  Gupta.
-
-- CVE-2026-45232 (CVSS v3.1 3.1, LOW): Off-by-one out-of-bounds stack
-  write in the rsync client's HTTP CONNECT proxy handler
-  (`establish_proxy_connection()` in `socket.c`).  After issuing the
-  CONNECT request, rsync read the proxy's first response line one
-  byte at a time into a 1024-byte stack buffer with the bound
-  `cp < &buffer[sizeof buffer - 1]`.  If the proxy (or a MITM in
-  front of it) returned 1023+ bytes on that first line without a
-  newline terminator, `cp` exited the loop pointing at a buffer slot
-  the loop never wrote, leaving `*cp` holding stale stack data from
-  the earlier `snprintf()` of the outgoing CONNECT request.  The
-  post-loop logic then wrote a single `\0` one byte past the end of
-  the buffer on the stack.  Reach is client-side only, and only when
-  `RSYNC_PROXY` is set so rsync tunnels an `rsync://` connection
-  through an HTTP CONNECT proxy.  The written byte is always `\0`
-  and the offset is fixed by the buffer size, not attacker-chosen,
-  so this is not an arbitrary-write primitive: practical impact is
-  corruption of one adjacent stack byte and possible later
-  misbehaviour or crash.  The fix detects the "buffer filled without
-  finding `\n`" case explicitly by position and refuses the response
-  with "proxy response line too long".  Reported by Aisle Research
-  via Michal Ruprich (rsync-3.4.1-2.el10 QE).
-
-In addition to the six CVE fixes, this release adds defence-in-depth
-hardening on several adjacent paths: bounded wire-supplied counts and
-lengths in flist/io/acls/xattrs, a guard against length underflow in
-cumulative `snprintf()` callers, a parent block-index bounds check on
-the receiver, a NULL check in `read_delay_line()`, a lower ceiling on
-`MAX_WIRE_DEL_STAT` to avoid signed-int overflow in the
-`read_del_stats()` accumulator, rejection of hyphen-prefixed
-remote-shell hostnames (defence-in-depth against argv-injection in
-tooling that forwards untrusted input into the hostspec position;
-reported by Aisle Research via Michal Ruprich), and a NULL-check on
-`localtime_r()` in `timestring()` to keep a malicious server from
-crashing the client by advertising a file with an out-of-range
-modtime.
-
-### BUG FIXES:
-
-- Fixed a regression introduced by the 3.4.0 secure_relative_open()
-  CVE fix where legitimate directory symlinks on the receiver side
-  (e.g. when using `-K` / `--copy-dirlinks`) caused "failed
-  verification -- update discarded" errors on delta transfers. The
-  old code rejected every symlink in the path with a per-component
-  `O_NOFOLLOW` walk; the receiver now uses kernel-enforced "stay
-  below dirfd" path resolution where available. Fixes #715.
-
-### PORTABILITY / BUILD:
-
-- secure_relative_open() now uses `openat2(RESOLVE_BENEATH |
-  RESOLVE_NO_MAGICLINKS)` on Linux 5.6+, and `openat()` with
-  `O_RESOLVE_BENEATH` on FreeBSD 13+ and macOS 15+ (Sequoia) /
-  iOS 18+. The kernel rejects ".." escapes, absolute symlinks, and
-  symlinks whose target lies outside the starting directory, while
-  still following symlinks that resolve within it -- the same
-  trade-off that fixes the issue #715 regression without weakening
-  the original CVE protection. Other platforms (Solaris, OpenBSD,
-  NetBSD, Cygwin) retain the previous per-component `O_NOFOLLOW`
-  walk; on those platforms the issue #715 regression remains
-  visible.
-
-- testsuite/xattrs: ignore `SUNWattr_*` in the Solaris `xls`
-  helper.
-
-### DEVELOPER RELATED:
-
-- Added testsuite/symlink-dirlink-basis.test (taken from PR #864
-  by Samuel Henrique) covering the issue #715 regression and
-  several edge cases (`--backup`, `--inplace`, `--partial-dir`
-  with protocol < 29, top-level files). The test skips on
-  platforms without a RESOLVE_BENEATH equivalent.
-
-- Added regression tests for the new security fixes:
-  `chmod-symlink-race.test`, `chdir-symlink-race.test`,
-  `bare-do-open-symlink-race.test`, `alt-dest-symlink-race.test`,
-  `copy-dest-source-symlink.test`, `sender-flist-symlink-leak.test`,
-  `secure-relpath-validation.test`, `daemon-chroot-acl.test` and
-  `daemon-refuse-compress.test`. The symlink-race tests skip on
-  Cygwin, Solaris, OpenBSD and NetBSD (no RESOLVE_BENEATH
-  equivalent on those platforms).
-
-- runtests.py now errors early with a clear message when any of
-  the test helper programs (`tls`, `trimslash`, `t_unsafe`,
-  `t_chmod_secure`, `t_secure_relpath`, `wildtest`, `getgroups`,
-  `getfsdev`) are missing, instead of letting many tests fail with
-  confusing "not found" errors.
-
-- Added OpenBSD and NetBSD CI jobs that run `make check` on those
-  platforms.
-
-- Added Ubuntu 22.04 and AlmaLinux 8 CI workflows so future
-  backports to the two mainstream LTS families build and test on
-  the same CI surface as trunk.
-
-- testsuite/protected-regular.test now runs unprivileged via
-  `unshare` with user-namespace UID mapping, falling back to skip
-  if `unshare`/`uidmap` is not available; previously it required
-  real root.
-
-- Added `symlink-dirlink-basis` to the Cygwin CI's expected-skipped
-  list.
-
-- Removed the old release system (replaced by the new release
-  script in 3.4.2).

-
-### SECURITY RELATED:
-
-Several security-relevant defects were reported and fixed since 3.4.1.
-None were assigned a CVE — rsync's fork-per-connection design scopes
-the impact of each of these to the attacker's own connection, which is
-equivalent to the client closing the socket itself — but they are
-fixed here as a matter of hygiene and to reduce the chances of a
-future exploitable combination.  Many thanks to the external
-researchers who reported these issues.
-
-- Fixed a signed integer overflow in the PROXY protocol v2 header
-  parser: a negative `len` field could bypass the size check and cause
-  a stack buffer overflow in `read_buf()`.  Reported by John Walker of
-  ZeroPath.
-
-- Fixed an invalid access to the files array.  Reported by Calum
-  Hutton of Rapid7.
-
-- Reject negative token values in the compressed-stream token
-  decoder; a negative value could cause callers to misinterpret a
-  missing data pointer as literal data.  Reported by Will Sergeant.
-
-- Fixed the element count passed to the xattr `qsort()` (see
-  https://www.openwall.com/lists/oss-security/2026/04/16/2).
-
-- Fixed a buffer underflow in `clean_fname()`, and added a regression
-  test.
-
-- Fixed an uninitialized `mul_one` in the AVX2 get_checksum1 path
-  (undefined behaviour), and added a SIMD-checksum self-test that
-  cross-checks SSE2, SSSE3 and AVX2 against the C reference on both
-  aligned and unaligned buffers.
-
-- Fixed an uninitialized `buf1` on the first call to
-  `get_checksum2()` in the MD4 path (fixes #673).
-
-- Zero all new memory from internal allocations: `my_alloc()` now uses
-  `calloc`, and `expand_item_list()` zeros the expanded portion after
-  `realloc`.  This gives more predictable behaviour if stale or
-  uninitialised memory is ever accidentally read.
-
-### BUG FIXES:
-
-- Call `tzset()` before chroot so that log timestamps continue to
-  reflect the configured local timezone after the daemon chroots
-  (glibc needs `/etc/localtime`, which is unreachable post-chroot).
-
-- Use the correct time when writing to the log file.
-
-- Do not clear `DISPLAY` unconditionally.
-
-- Fixed a Y2038 bug in `syscall.c` by replacing the `Int32x32To64`
-  macro (which truncates its arguments to 32 bits) with a plain
-  64-bit multiplication.
-
-- Fixed ACL ID mapping for non-root users (closes #618).
-
-- Fixed handling of objects with many xattrs on FreeBSD.
-
-- Fixed `--open-noatime` not taking effect when opening regular
-  files: `O_NOATIME` is now also passed to `do_open_nofollow()`, which
-  has been used for regular files since the CVE fix "fixed symlink
-  race condition in sender".
-
-- Ignore "directory has vanished" errors.
-
-- Fixed the removal of multiple leading slashes.
-
-- Added the missing `--dirs` long option.
-
-- Fixed a segfault if `poptGetContext()` returns NULL (e.g. under
-  OOM) by not passing NULL to `poptReadDefaultConfig()`.  Reported by
-  Ronnie Sahlberg; found with `malloc-fail-tester`.
-
-- Fixed a build error on ia64 NonStop (which treats missing
-  prototypes as an error, not a warning).
-
-- Fixed a flaky hardlinks test (fixes #735).
-
-### ENHANCEMENTS:
-
-- Added multi-threaded `zstd` compression, gated by a new
-  `--compress-threads=N` option, with validation and man-page
-  coverage.
-
-- Documented the `temp dir` parameter in the rsyncd.conf man page
-  (fixes #820).
-
-- Improved rendering of interior dashes in long-option names in
-  `md-convert` (perhaps fixes #686).
-
-### PORTABILITY / BUILD:
-
-- Fixed glibc 2.43 const-preserving overloads of `strtok()`,
-  `strchr()` etc. by declaring the affected locals with the right
-  constness.  Contributed by Holger Hoffstätte.
-
-- Converted the bundled zlib 1.2.8 from K&R-style function
-  definitions to ANSI prototypes, so it builds with clang 16+.
-
-- Avoid using `bool` as an identifier; it is a keyword in C23.
-
-- `configure.ac`: check for xattr functions in libc first and only
-  fall back to `-lattr`, avoiding spurious overlinking when `-lattr`
-  happens to be installed.  Contributed by Eli Schwartz.
-
-- Made the build reproducible by honouring `SOURCE_DATE_EPOCH` for
-  the manpage date.
-
-- Removed obsolete `popt/findme.c` and `popt/findme.h` that upstream
-  popt 1.14 folded into `popt.c` (fixes #710).  Contributed by Alan
-  Coopersmith.
-
-### INTERNAL:
-
-- Made many module-global variables `const` so they can live in
-  `.rodata` and enable additional compiler optimization.
-
-### DEVELOPER RELATED:
-
-- Replaced `runtests.sh` with `runtests.py`, a Python test runner
-  that supports `--valgrind` (with per-process log files so valgrind
-  output no longer interferes with output comparisons) and
-  `-j/--parallel` execution for roughly a 7× speed-up on typical
-  hardware.
-
-- Added a SIMD checksum self-test and a `clean-fname-underflow`
-  regression test.
-
-- Various CI fixes for macOS and Cygwin (including adding
-  `simd-checksum` to the expected-skipped lists on platforms without
-  SIMD), and tests now run on `ubuntu-latest`.
-
-- removed support for the unmaintained rsync-patches archive

- * Android-specific helpers.
- *
- * openat2() usability probe
- * -------------------------
- * openat2(2) is invoked directly via syscall() because the C library lacked a
- * wrapper for it for years.  Under a seccomp filter that uses
- * SECCOMP_RET_TRAP -- as the Android application sandbox does -- a disallowed
- * syscall raises SIGSYS and *kills the process* rather than failing with
- * ENOSYS, so inspecting errno after the call is too late.  We therefore probe
- * openat2() once, behind a temporary SIGSYS handler, so a trapped syscall is
- * caught and secure_relative_open_linux() can fall back to the portable
- * per-component O_NOFOLLOW resolver instead of the whole process dying.
- *
- * This is only needed on Android, so the probe body is compiled only there.
- * __ANDROID__ is defined by Bionic's headers and reflects the *target*, not
- * the build host: it is set both for NDK cross-compiles (from a Linux/macOS
- * host) and for native Termux builds, and is unset on every other platform.
- * That makes it a reliable compile-time switch for cross builds -- there is
- * nothing to detect in configure.  Everywhere else openat2() is never
- * seccomp-trapped to SIGSYS (a missing syscall simply returns ENOSYS), so
- * openat2_usable() collapses to a constant 1 with no run-time cost.

+Handling the rsync SGML documentation
+
+rsync documentation is now primarily in Docbook format.  Docbook is an
+SGML/XML documentation format that is becoming standard on free
+operating systems.  It's also used for Samba documentation.
+
+The SGML files are source code that can be translated into various
+useful output formats, primarily PDF, HTML, Postscript and plain text.  
+
+To do this transformation on Debian, you should install the
+docbook-utils package.  Having done that, you can say 
+
+  docbook2pdf rsync.sgml
+
+and so on.
+
+On other systems you probably need James Clark's "sp" and "JadeTeX"
+packages.  Work it out for yourself and send a note to the mailing
+list.

+	<answer>
+	  <para>
+	    On gcc, rsync builds by default with debug symbols
+	    included.  If you strip both executables, they should end
+	    up about the same size.  (Use <command>make
+	    install-strip</command>.)

+	<question>
+	  <para>Is rsync useful for a single large file like an ISO image?</para>
+	</question>
+	<answer>
+	  <para>
+	    Yes, but note the following:
+
+	  <para>
+   Background: A common use of rsync is to update a file (or set of files) in one location from a more
+   correct or up-to-date copy in another location, taking advantage of portions of the files that are
+   identical to speed up the process. (Note that rsync will transfer a file in its entirety if no copy
+   exists at the destination.)
+
+	  <para>
+   (This discussion is written in terms of updating a local copy of a file from a correct file in a
+   remote location, although rsync can work in either direction.)
+
+	  <para>
+   The file to be updated (the local file) must be in a destination directory that has enough space for
+   two copies of the file. (In addition, keep an extra copy of the file to be updated in a different
+   location for safety -- see the discussion (below) about rsync's behavior when the rsync process is
+   interrupted before completion.)
+
+	  <para>
+   The local file must have the same name as the remote file being sync'd to (I think?). If you are
+   trying to upgrade an iso from, for example, beta1 to beta2, rename the local file to the same name
+   as the beta2 file. *(This is a useful thing to do -- only the changed portions will be
+   transmitted.)*
+
+	  <para>
+   The extra copy of the local file kept in a different location is because of rsync's behavior if
+   interrupted before completion:
+
+	  <para>
+   * If you specify the --partial option and rsync is interrupted, rsync will save the partially
+   rsync'd file and throw away the original local copy. (The partially rsync'd file is correct but
+   truncated.) If rsync is restarted, it will not have a local copy of the file to check for duplicate
+   blocks beyond the section of the file that has already been rsync'd, thus the remainder of the rsync
+   process will be a "pure transfer" of the file rather than taking advantage of the rsync algorithm.
+
+	  <para>
+   * If you don't specify the --partial option and rsync is interrupted, rsync will throw away the
+   partially rsync'd file, and, when rsync is restarted starts the rsync process over from the
+   beginning.
+
+	  <para>
+   Which of these is most desirable depends on the degree of commonality between the local and remote
+   copies of the file *and how much progress was made before the interruption*.
+
+	  <para>
+   The ideal approach after an interruption would be to create a new file by taking the original file
+   and deleting a portion equal in size to the portion already rsync'd and then appending *the
+   remaining* portion to the portion of the file that has already been rsync'd. (There has been some
+   discussion about creating an option to do this automatically.)
+
+   The --compare-dest option is useful when transferring multiple files, but is of no benefit in
+   transferring a single file. (AFAIK)

-# Old rsync version archive
-
-Static rsync binaries built from historical release tags. Two uses:
-
-1. **Cross-version behaviour checks** — confirming whether a behaviour a user
-   reported on an old release is version-specific or option-driven.
-2. **The version-mixing test suite** — `runtests.py --rsync-bin2=...` runs the
-   current code against one of these as the daemon / remote-shell peer; CI
-   (`.github/workflows/ubuntu-version-mix.yml`) does this for every binary
-   here against the per-version manifests in `testsuite/expect/`.
-
-Binaries are **statically linked** so they run regardless of the host's
-shared libraries, and named `rsync_<version>`:
-
-| Binary         | Version | Protocol | Notes                                   |
-|----------------|---------|----------|-----------------------------------------|
-| `rsync_2.6.0`  | 2.6.0   | 27       | 2004; needs autoconf regen (see below)  |
-| `rsync_3.0.0`  | 3.0.0   | 30       | 2008                                    |
-| `rsync_3.1.0`  | 3.1.0   | 31       | 2013                                    |
-| `rsync_3.1.3`  | 3.1.3   | 31       | Ubuntu 18.04 / Debian buster era (2018) |
-| `rsync_3.2.0`  | 3.2.0   | 31       | 2020 (zstd/lz4/xxhash negotiation added)|
-| `rsync_3.2.7`  | 3.2.7   | 31       | 2022                                    |
-| `rsync_3.3.0`  | 3.3.0   | 31       | 2024                                    |

-
-These are every `x.y.0` release from 2.6.0 (2004) onward plus a few point
-releases. 2.6.0 is the practical floor: older tags need progressively more
-porting to build on a current toolchain.
-
-All built `--disable-openssl` and with `_FORTIFY_SOURCE` disabled (see below);
-xxhash/zstd/lz4 are compiled in where the version supports them.
-
-## Adding a version
-
-```bash
-./build_static.sh 3.2.7            # uses git tag v3.2.7
-./build_static.sh 3.0.9 v3.0.9     # explicit tag if naming differs
-```
-
-The script checks out the tag into a throwaway `git worktree`, applies the
-minimal patches needed to compile old sources on a modern toolchain, links
-statically, verifies the result is static and reports the requested version,
-then installs `rsync_<version>` here and removes the worktree.
-
-Override the source repo with `RSYNC_REPO=/path/to/rsync ./build_static.sh ...`
-(defaults to `../rsync.4`).
-
-## Why the patches?
-
-Modern GCC (>= 14, C23 default) and glibc reject things old rsync relied on.
-`build_static.sh` handles these, each guarded so it's a no-op when not needed:
-
-1. **K&R `lseek64()` redeclaration** in `syscall.c` clashes with glibc's real
-   prototype — removed.
-2. **`gettimeofday()`** — glibc only has the 2-arg form; configure misdetects
-   the 1-arg form, so `HAVE_GETTIMEOFDAY_TZ` is forced on in `config.h`.
-3. **C23 `()` == `(void)`** breaks K&R prototypes called with arguments
-   (`qsort` comparator, `pool->bomb`, etc.) — built with `-std=gnu11`.
-4. Assorted modern `-Werror` promotions (incompatible pointer types, implicit
-   declarations) downgraded to warnings; bundled zlib/popt used to keep the
-   static link self-contained.
-
-5. **OpenSSL (3.2+)** is disabled with `--disable-openssl`: linking
-   `libcrypto.a` statically drags in jitterentropy (`jent_*`) and zlib's
-   `uncompress` (OpenSSL's COMP module), which don't resolve here. OpenSSL only
-   provided optional MD4/MD5, which rsync implements natively, so checksum
-   behaviour is unaffected.
-
-6. **`_FORTIFY_SOURCE` disabled** (`-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0`):
-   modern Ubuntu defaults it to `=3`, whose stricter object-size checks turn
-   latent (historically benign) over-reads in OLD rsync into hard
-   `*** buffer overflow detected ***` aborts when the binary runs as a
-   server/daemon — which made e.g. 3.1.3 and 3.2.7 unusable as peers. Disabling
-   it makes the archival binaries behave as the released versions did.
-
-7. **Pre-3.0 tags (e.g. 2.6.0)** ship `configure.in`, not a generated
-   `configure`. The script runs `autoheader`/`autoconf` to generate it, after
-   neutralizing the `AC_CHECK_FUNCS(fn,,AC_LIBOBJ(lib/...))` fallbacks for
-   `inet_ntop`/`inet_pton`/`getaddrinfo`/`getnameinfo` — modern autoconf emits
-   broken shell for those never-taken branches (the funcs exist in glibc). It
-   also generates `proto.h` (no make rule in that era) and stubs the vendored
-   `lib/addrinfo.h` the tag dropped (modern glibc supplies `struct addrinfo`).
-   All guarded so they no-op on 3.x.
-
-Newer versions may need fewer or different tweaks; if a build fails, the
-script prints the first compiler errors from its log.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. &lt;<a href="https://fsf.org/">https://fsf.org/</a>&gt;
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    &lt;one line to give the program's name and a brief idea of what it does.&gt;
-    Copyright (C) &lt;year&gt;  &lt;name of author&gt;
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see &lt;<a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>&gt;.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    &lt;program&gt;  Copyright (C) &lt;year&gt;  &lt;name of author&gt;
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-&lt;<a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>&gt;.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-     51 Franklin Street - Fifth Floor, Boston, MA 02110-1301, USA.
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-<hr>
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-<hr>
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-<hr>
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-<hr>
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    &lt;one line to give the program's name and a brief idea of what it does.&gt;
-    Copyright (C) &lt;year&gt;  &lt;name of author&gt;
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year  name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  &lt;signature of Ty Coon&gt;, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-rsync error: error in rsync protocol data stream (code 12) at io.c(463)

-for details on how you can try to figure out what is going wrong.
-
-<hr>
-<h3><a name=2>rsync recopies the same files</a></h3>
-
-<p>Some people occasionally report that rsync copies too many files when
-they expect it to copy only a few. In most cases the explanation is
-that you forgot to include the --times (-t) option in the original copy,
-so rsync is forced to (efficiently) transfer every file that differs in
-its modified time to discover what data (if any) has changed.
-
-<p>Another common cause involves sending files to an Microsoft filesystem:
-if the file's modified time is an odd value but the receiving filesystem
-can only store even values, then rsync will re-transfer too many files.
-You can avoid this by specifying the --modify-window=1 option.
-
-<p>Yet another periodic case can happen when daylight-savings time
-changes if your OS+filesystem saves file times in local time instead of
-UTC.  For a full explanation of this and some suggestions on how to
-avoid them problem, see <a href="daylight-savings.html">this document</a>.
-
-<p>Something else that can trip up rsync is a filesystem changeing the
-filename behind the scenes.  This can happen when a filesystem changes
-an all-uppercase name into lowercase, or when it decomposes UTF-8 behind
-your back.
-
-<blockquote>
-
-<p>An example of the latter can occur with HFS+ on Mac OS X:  if you
-copy a directory with a file that has a UTF-8 character sequence in it,
-say a 2-byte umlaut-u (\0303\0274), the file will get that character
-stored by the filesystem using 3 bytes (\0165\0314\0210), and rsync will
-not know that these differing filenames are the same file (it will, in
-fact, remove a prior copy of the file if --delete is enabled, and then
-recreate it).
-
-<p>You can avoid a charset problem by passing an appropriate --iconv
-option to rsync that tells it what character-set the source files are,
-and what character-set the destination files get stored in.  For
-instance, the above Mac OS X problem would be dealt with by using
---iconv=UTF-8,UTF8-MAC (UTF8-MAC is a pseudo-charset recognized by Mac
-OS X iconv in which all characters are decomposed).
-
-</blockquote>
-
-<p>If you think that rsync is copying too many files, look at the
-itemized output (-i) to see why rsync is doing the update (e.g. the 't'
-flag indicates that the time differs, or all pluses indicates that rsync
-thinks the file doesn't exist).  You can also look at the stats produced
-with -v and see if rsync is really sending all the data.  See also the
---checksum (-c) option for one way to avoid the extra copying of files
-that don't have synchronized modified times (but keep in mind that the
--c option eats lots of disk I/O, and can be rather slow).
-
-<hr>
-<h3><a name=3>is your shell clean</a></h3>
-
-<p>The "is your shell clean" message and the "protocol mismatch" message
-are usually caused by having some sort of program in your .cshrc, .profile,
-.bashrc or equivalent file that writes a message every time you connect
-using a remote-shell program (such as ssh or rsh).  Data written in this
-way corrupts the rsync data stream. rsync detects this at startup and
-produces those error messages.  However, if you are using rsync-daemon
-syntax (host::path or rsync://) without using a remote-shell program (no
---rsh or -e option), there is not remote-shell program involved, and the
-problem is probably caused by an error on the daemon side (so check the
-daemon logs).
-
-<p>A good way to test if your remote-shell connection is clean is to try
-something like this (use ssh or rsh, as appropriate):
-
-<blockquote><pre>ssh remotesystem /bin/true &gt; test.dat</pre></blockquote>
-
-<p>That should create a file called test.dat with nothing in it. If
-test.dat is not of zero length then your shell is not clean.  Look at the
-contents of test.dat to see what was sent. Look at all the startup files on
-remotesystem to try and find the problem.
-
-<hr>
-<h3><a name=4>memory usage</a></h3>
-
-<p>Rsync versions before 3.0.0 always build the entire list of files to be
-transferred at the beginning and hold it in memory for the entire run.  Rsync
-needs about 100 bytes to store all the relevant information for one file,
-so (for example) a run with 800,000 files would consume about 80M of
-memory.  -H and --delete increase the memory usage further.
-
-<p>Version 3.0.0 slightly reduced the memory used per file by not storing fields
-not needed for a particular file.  It also introduced an incremental recursion
-mode that builds the file list in chunks and holds each chunk in memory only as
-long as it is needed.  This mode dramatically reduces memory usage, but it
-only works provided that both sides are 3.0.0 or newer and certain options that
-rsync currently can't handle in this mode are not being used.
-
-<hr>
-<h3><a name=5>out of memory</a></h3>
-
-<p>The usual reason for "out of memory" when running rsync is that you are
-transferring a _very_ large number of files.  The size of the files doesn't
-matter, only the total number of files.  If memory is a problem, first try to
-use the incremental recursion mode: upgrade both sides to rsync 3.0.0 or
-newer and avoid options that disable incremental recursion (e.g., use
-<tt>--delete-delay</tt> instead of <tt>--delete-after</tt>).  If this is not
-possible, you can break the rsync run into smaller chunks operating on
-individual subdirectories using <tt>--relative</tt> and/or exclude rules.
-
-<hr>
-<h3><a name=6>rsync through a firewall</a></h3>
-
-<p>If you have a setup where there is no way to directly connect two
-systems for an rsync transfer, there are several ways to get a firewall
-system to act as an intermediary in the transfer.  You'll find full details
-on the <a href="firewall.html">firewall methods</a> page.
-
-<hr>
-<h3><a name=7>rsync and cron</a></h3>
-
-<p>On some systems (notably SunOS4) cron supplies what looks like a socket
-to rsync, so rsync thinks that stdin is a socket. This means that if you
-start rsync with the --daemon switch from a cron job you end up rsync
-thinking it has been started from inetd. The fix is simple&mdash;just
-redirect stdin from /dev/null in your cron job.
-
-<hr>
-<h3><a name=8>rsync: Command not found</a></h3>
-
-<p>This error is produced when the remote shell is unable to locate the rsync
-binary in your path. There are 3 possible solutions:
-
-<ol>
-
-<li>install rsync in a "standard" location that is in your remote path. 
-
-<li>modify your .cshrc, .bashrc etc on the remote system to include the path
-that rsync is in
-
-<li>use the --rsync-path option to explicitly specify the path on the
-remote system where rsync is installed
-
-</ol>
-
-<p>You may echo find the command:
-
-<blockquote><pre>ssh host 'echo $PATH'</pre></blockquote>
-
-<p>for determining what your remote path is.
-
-<hr>
-<h3><a name=9>spaces in filenames</a></h3>
-
-<p>Can rsync copy files with spaces in them?
-
-<p>Short answer: Yes, rsync can handle filenames with spaces.
-
-<p>Long answer: 
-
-<p>Rsync handles spaces just like any other unix command line application.
-Within the code spaces are treated just like any other character so a
-filename with a space is no different from a filename with any other
-character in it.
-
-<p>The problem of spaces is in the argv processing done to interpret the
-command line.  As with any other unix application you have to escape spaces
-in some way on the command line or they will be used to separate arguments. 
-
-<p>It is slightly trickier in rsync (and other remote-copy programs like
-scp) because rsync sends a command line to the remote system to launch the
-peer copy of rsync (this assumes that we're not talking about daemon mode,
-which is not affected by this problem because no remote shell is involved
-in the reception of the filenames).  The command line is interpreted by the
-remote shell and thus the spaces need to arrive on the remote system
-escaped so that the shell doesn't split such filenames into multiple
-arguments.
-
-<p>For example:
-
-<blockquote><pre>rsync -av host:'a long filename' /tmp/</pre></blockquote>
-
-<p>This is usually a request for rsync to copy 3 files from the remote
-system, "a", "long", and "filename" (the only exception to this is for a
-system running a shell that does not word-split arguments in its commands,
-and that is exceedingly rare).  If you wanted to request a single file with
-spaces, you need to get some kind of space-quoting characters to the remote
-shell that is running the remote rsync command.  The following commands
-should all work:
-
-<blockquote><pre>rsync -av host:'"a long filename"' /tmp/
-rsync -av host:'a\ long\ filename' /tmp/
-rsync -av host:a\\\ long\\\ filename /tmp/</pre></blockquote>
-
-<p>You might also like to use a '?' in place of a space as long as there
-are no other matching filenames than the one with spaces (since '?' matches
-any character):
-
-<blockquote><pre>rsync -av host:a?long?filename /tmp/</pre></blockquote>
-
-<p>As long as you know that the remote filenames on the command line
-are interpreted by the remote shell then it all works fine. 
-
-<hr>
-<h3><a name=10>ignore "vanished files" warning</a></h3>
-
-<p>Some folks would like to ignore the "vanished files" warning, which
-manifests as an exit-code 24.  The easiest way to do this is to create
-a shell script wrapper.  For instance, name this something like
-"rsync-no24":
-
-<blockquote><pre>#!/bin/sh
-rsync "$@"
-e=$?
-if test $e = 24; then
-    exit 0
-fi
-exit $e</pre></blockquote>
-
-<hr>
-<h3><a name=11>read-only file system</a></h3>
-
-<p>If you get "Read-only file system" as an error when sending to a rsync
-daemon then you probably forgot to set "read only = no" for that module.
-
-<hr>
-<h3><a name=12>multiplexing overflow 101:7104843</a></h3>
-
-<p>This mysterious error, or the similar "invalid message 101:7104843", can
-happen if one of the rsync processes is killed for some reason and a message
-beginning with the four characters "Kill" gets inserted into the protocol
-stream as a result.  To solve the problem, you'll need to figure out why rsync
-is being killed.
-
-<hr>
-<h3><a name=13>inflate (token) returned -5</a></h3>
-
-This error means that rsync failed to handle an expected error from the
-compression code for a file that happened to be transferred with a block size
-of 32816 bytes.  You can avoid this issue for the affected file by transferring
-it with a manually-set block size (e.g. --block-size=33000), or by upgrading
-the receiving side to rsync 3.0.7.

-
-<h1>How the DST Change can adversely affect FAT filesystems</h1>
-
-<p>
-The vernal and autumnal transitions to and from daylight-savings
-time have important implications
-for those with Microsoft systems and use utilities that
-compare file timestamps on different filesystem types or
-with filesystems on other operating systems that can lead to
-a problem in how the file's date is handled.
-This problem lies in the way FAT filesystems stores
-timestamps and how Windows converts between local time and
-UTC. 
-
-<h2>Background</h2>
-
-<p>
-In UNIX and UNIX-like systems (such as Linux) file timestamps
-are stored in UTC (universal time) and are only converted to
-local-time by user-space programs for display purposes.&nbsp; At
-the system call level all time values are in UTC and
-utilities that compare timestamps do so in UTC.&nbsp; Also, the
-standard UTC-&gt;local and local-&gt;UTC conversion functions are
-aware of DST and conversions reflect this so that if a
-timestamp was recorded during ST it will be converted using
-the ST offset even when the current system time is DST.
-
-<p>
-In Windows things are not so simple.&nbsp; Windows operates in
-local-time.&nbsp; Timestamps in the various FAT derived
-filesystems are stored in local-time.&nbsp; Timestamps in NTFS
-filesystems are stored in UTC.&nbsp; This inconsistency is
-further complicated by the fact that the conversion routines
-used are not DST aware.&nbsp; Instead of being DST aware the
-system has a fixed offset to convert between local-time and
-UTC regardless of the date in the timestamp.&nbsp; This fixed
-offset is calculated at boot time and only changed when
-systems transition to or from DST.&nbsp; As a result the apparent
-modification time of a file on NTFS as reported in a windows
-utility will change by one hour when reported in local-time
-and FAT based files when reported in UTC.
-
-<p>
-The difficulty that this produces is that any utilities that
-compare timestamps between FAT and NTFS filesystems or
-between Windows and other platforms will view files that
-have not changed as having a different modified time.&nbsp; Among other things
-this will affect rsync, rdiff, unison, wget, and make.&nbsp; However,
-for the purposes of this document, we will only discuss rsync.
-
-<p>
-With the reduced cost of hard disks many newer backup
-systems are using hard disk based storage and take advantage
-of timestamp comparison to detect file changes for the sake
-of efficiency.&nbsp; Rsync is probably premier in this role and
-is used by a fair number of free and even commercial backup
-systems as well as being the basis for many home-brew backup
-solutions.
-
-<p>
-With rsync and similar systems the effect of this is that
-every file will appear to have been changed.&nbsp; The result is
-any space savings associated with linking (--link-dest) or
-with decremental backup approaches (--compare-dest and
---backup-dir) will be defeated.&nbsp; Perhaps worse, because
-every file will appear to have changed the time required to
-do a backup or a non-backup rsync will be much longer than
-normal.&nbsp; In some cases backups that normally complete in
-less than one hour can take several days.
-
-<p>
-So what can be done about it?  Several things, there are
-ways to merely mitigate the problem, to correct it and finally
-to prevent the problem entirely.
-
-<h2>Mitigation</h2>
-
-<p>
-Rsync has a --modify-window option.&nbsp; Many of you already use
---modify-window=1 to cope with the fact that windows often
-stores timestamps with a two second resolution.&nbsp; Using a
---modify-window=3601 will cause rsync to ignore timestamp
-differences of up to one hour.
-
-<p>
-This if often not particularly dangerous because a file would have to
-be changed, synced and changed again without changing size
-within a single hour and have no subsequent changes for this copy
-to miss a file change.&nbsp; However, for some systems any such risk is
-unacceptable, so other solutions are needed.
-
-<h2>Correcting the Timestamps</h2>
-
-<p>
-There are two ways to correct.
-
-<p>For the first run after the time change, you can run rsync with the
---checksum option in order to ensure that only files that have a changed
-checksum get transferred, and update the modified time on all unchanged
-files.&nbsp; This option has the drawback that it increases disk I/O by
-a large amount on both the sending and receiving side, slowing down the
-copy.
-
-<p>
-The other way to correct things is to change the timestamps
-on the files on the backup server before doing a copy after a
-time change has occurred.
-
-<p>
-Included here is an example perl script that will change the
-timestamps of files in a list on standard-input.&nbsp; Whether
-you use a positive or negative shift will depend on which
-end you decide to adjust.
-
-<p>
-This is an example of how to use the script:
-
-<blockquote><pre>
-touch -d '01:00 13-apr-03' /tmp/cmpfile
-find . -type f ! -newer /tmp/cmpfile | shifttime.pl 3600
-</pre></blockquote>
-
-<hr>
-<pre>
-#!/usr/bin/perl
-use strict;
-
-my $offset = shift() + 0;
-die &quot;Usage: $0 OFFSET_SECONDS\n&quot; unless $offset;
-
-while (&lt;&gt;) {
-    chomp;
-    my $mtime = (stat $_)[9];
-    next unless $mtime;
-    $mtime += $offset;
-    utime $mtime, $mtime, $_;
-}
-</pre>
-<hr>
-
-<h2>Prevention</h2>
-
-<p>
-To prevent the problem in the first place you need to
-prevent changing to DST.&nbsp; This can be done by either running
-the windows system in UTC, by disabling DST and changing
-the system time manually twice each year, or by avoiding the use
-of the FAT filesystem (perhaps by switching to a different OS).
-
-
-<h2>Notes and References</h2>
-
-<p>
-Here are some references that Wayne Piekarski collected
-while researching this problem.&nbsp; They contain a lot of
-information about the ways that Windows deals with
-timestamps on NTFS and FAT filesystems.

-<h2>Source-code releases</h2>
-
-<p>You can grab the latest source code and other related files in a variety of ways:
-
-<ul>
-
-<li><p>The latest version is linked on the <a href="https://rsync.samba.org/">main page</a>.
-
-<li><p>A directory listing of these latest files and various historical release and diff files
-are available via <a href="https://download.samba.org/pub/rsync/">this web page</a> and
-via <i>anonymous SSL rsync</i> using this command:
-<p><code><small>rsync-ssl rsync://download.samba.org/rsyncftp/</small></code></p>
-
-<li><p>You can also get .zip and .tar.gz versions of the various git repo's release
-tags via the <a href="https://github.com/RsyncProject/rsync/tags">rsync GitHub tags page</a>
-and the associated patches via the
-<a href="https://github.com/RsyncProject/rsync-patches/tags">rsync-patches GitHub tags page</a>.
-Keep in mind that these git-derived files do NOT come with the extra generated files that are included
-in the official release tar files.
-
-<li><p>You can browse the very latest source files, clone the source using git, or download a .zip file of the latest
-master branch from <a href="https://github.com/RsyncProject/rsync">rsync's GitHub page</a>.
-
-<li><p>The <a href="https://git.samba.org/?p=rsync.git">Samba git repo</a> is also available,
-though it might lag behind the GitHub repo every now and then.
-
-</ul>
-
-Once you have the source, read the <a
-href="https://download.samba.org/pub/rsync/INSTALL">INSTALL.md</a> file for
-details on some development libraries that you will need to build it.
-
-<h2>The GPG Signing Key</h2>
-
-The GPG signing key that is used to sign the release files is available from the public pgp key-server
-network.  If you have automatic key-fetching enabled, just running a normal
-"gpg&nbsp;--verify" will grab my key automatically.
-Or, feel free to grab <a href="https://opencoder.net/WayneDavison.key">the gpp
-  key for Wayne Davison</a> manually.<p>
-
-From 3.4.0 and later releases will be signed by Andrew
-Tridgell. Please fetch the key for andrew@tridgell.net from https://keys.openpgp.org/
-
-<h2>Binaries</h2>
-
-<p>Precompiled binaries are available in most modern OS distributions, so
-you should first check if you can install an rsync package via your
-standard package-install tools for your OS.
-
-<h3>Ubuntu</h3>
-
-<p>The rsync project maintains a Launchpad PPA that tracks upstream stable
-releases for the currently supported Ubuntu series (jammy 22.04 LTS,
-noble 24.04 LTS, questing 25.10, resolute 26.04 LTS).  This is the
-fastest way to get the latest upstream rsync on Ubuntu without waiting
-for the distro to update its packaged version:
-
-<p><code><small>sudo add-apt-repository ppa:rsyncproject/rsync<br>
-sudo apt update &amp;&amp; sudo apt install rsync</small></code>
-
-<p>See the <a href="https://launchpad.net/~rsyncproject/+archive/ubuntu/rsync">PPA page on Launchpad</a>
-for build status across architectures.
-
-<p>For testing the upcoming release, the project also maintains a
-<a href="https://launchpad.net/~rsyncproject/+archive/ubuntu/rsync-latest">rsync-latest PPA</a>
-that is rebuilt from the tip of the <a href="https://github.com/RsyncProject/rsync">git
-master branch</a>.  These are development snapshots: their version numbers
-(such as <code>3.5.0~git20260601...</code>) deliberately sort <em>below</em>
-the matching stable release, so mixing this with the stable PPA above will
-never silently move you from a release onto a snapshot:
-
-<p><code><small>sudo add-apt-repository ppa:rsyncproject/rsync-latest<br>
-sudo apt update &amp;&amp; sudo apt install rsync</small></code>
-
-<p>Use the stable PPA for production systems; the rsync-latest PPA is for
-testing the master branch and may contain unreleased changes.
-
-<p>The <a href="https://github.com/RsyncProject/rsync/actions">GitHub Actions
-page</a> has build events that each generate a few binary artifact zip files
-(just click through via the build's title to see them).  The actions page is
-also linked via the various green build-status icons on the web pages here.
-These builds use the newest libraries, such as xxhash checksums and zstd
-compression, and are dynamically linked, so you may need to install some
-official library packages for your distribution.  If you're curious how the
-build was done, you can look at the build rules in the "Workflow file" tab.
-See the <a href="https://download.samba.org/pub/rsync/INSTALL">INSTALL.md</a>
-file for some package name hints, though you can use the non-devel versions of
-the various lib packages and ignore the gcc/autoconf/awk packages.
-
-<p>There are also packages available from some <b>3rd-parties</b> (note that we
-cannot vouch for 3rd parties, so use a source that you trust):
-
-<ul>
-
-<li><p><a href="https://www.cygwin.com/">Cygwin</a> is a Posix runtime for MS
-Windows that includes rsync among their many packages.</p></li>
-
-<li><p><a href="https://www.itefix.net/cwrsync">cwRsync</a> is a native
-packaging of rsync for MS Windows (they appear to only provide paid releases,
-though).</p></li>
-
-</ul>
-
-<h2>Git source vs Release files</h2>
-
-The release tar files come with a few generated files that are not checked in to git.
-These mainly include the man pages and the configure related files.  To make use of
-the git-derived files you will need autoconf, autoheader, and a version of python3
-that has the commonmark lib (OR cmarkgfm).  If you have trouble with setting up the
-those required files, you can try running "./prepare-source fetchgen" to grab the
-very latest generated files that were created from the latest commit into the master
-branch.
-
-<p> <b>Note:</b> Since the source repository is a work in progress it may, at
-times, not compile or fail in various ways, though it is usually pretty good.
-
-<h2>Source repository patches</h2>
-
-<p>There are also various patch files in the "rsync-patches" repository that
-represent either some work-in-progress features or features that are considered
-to be a little too fringe-interest for the main release.  See the github link
-above for how to look around at what is available, or snag a release tar file.
-The maintainer like to put the rsync-patches dir into his rsync checkout as a
-directory named "patches" and has some helper scripts for how to use local git
-branches to test and update the diffs.

-rsync is a file transfer program for Unix systems. rsync uses the
-"rsync algorithm" which provides a very fast method for bringing
-remote files into sync. It does this by sending just the differences
-in the files across the link, without requiring that both sets of
-files are present at one of the ends of the link beforehand. <p>
-
-Some features of rsync include
-
-<ul>
-<li> can update whole directory trees and filesystems
-<li> optionally preserves symbolic links, hard links, file ownership,
-permissions, devices and times
-<li> requires no special privileges to install
-<li> internal pipelining reduces latency for multiple files
-<li> can use rsh, ssh or direct sockets as the transport
-<li> supports <A HREF="http://dslab.lzu.edu.cn:8080/members/wangbj/wangbaojun/howtos/rsync-mirror-HOWTO/rsync-mirroring02.html">anonymous rsync</A> which is ideal for mirroring

-<TITLE>rsync firewall tunneling</TITLE>

-<!--#include virtual="header.html" -->
-
-<H2 align="center">Using rsync through a firewall</H2>
-
-<p>If you have a setup where there is no way to directly connect two
-systems for an rsync transfer, there are several ways to get a firewall
-system to act as an intermediary in the transfer.
-
-<p>This first method should work for any remote-shell (e.g. ssh, rsh, etc).
-The other methods are all targeted at ssh (which has a lot of flexibility
-in making a tunneled connection possible).
-
-<h4>Method 1 -- should work with any remote-shell</h4>
-
-<p>Use your remote shell (e.g. ssh) to access the middle system and have it
-use a remote shell to hop over to the actual target system.
-
-<p>To effect this extra hop, you'll need to make sure that the remote-shell
-connection from the middle system to the target system does not involve any
-tty-based user interaction (such as prompting for a password) because there
-is no way for the middle system to access the local user's tty.
-
-<p>One way that should work for all remote-shell programs is to enable host-based
-authentication, which would allow all connections from the middle system to
-the target system to succeed (when the username remains the same).
-However, this may not be a desirable setup.
-
-<p>A better method that works with ssh (and is very safe) is to setup an ssh
-key (see the ssh-keygen manpage) and ensure that ssh-agent forwarding is turned
-on in your ssh client config (e.g. "ForwardAgent&nbsp;yes").  You would put
-the public version of your key onto the middle and target systems (in the
-~/.ssh/authorized_keys file), and the private key on your local system (which
-I recommend you encrypt).  With this setup, a series of ssh connections that
-starts from the system where your private key is available will auto-authorize
-(after a pass-phrase prompt on the first system if your key is encrypted).
-See also ssh-agent for a way to keep a public key unlocked in memory for an
-extended time, and the keychain project for a way to manage a system-wide,
-per-user ssh-agent.
-
-<p>To test that you have things setup right, first test a series of
-remote-shell connections outside of rsync.  A command such as the following
-should work without issuing multiple prompts (use the appropriate remote-shell
-and the substitute the real hostnames for "middle" and "target", of course):
-
-<blockquote><pre>ssh middle ssh target uptime</pre></blockquote>
-
-<p>If you get a password/passphrase prompt to get into the first ("middle")
-system that's fine, but the extra hop needs to occur without any extra user
-interaction.
-
-<p>Once that's done, you can do an rsync copy like this:
-
-<blockquote><pre>rsync -av -e "ssh middle ssh" target:/src/ /dest/</pre></blockquote>
-
-<h4>Method 2 -- requires ssh and nc (netcat)</h4>
-
-<p>Assuming you're using ssh as your remote shell, you can configure ssh to
-use a proxy command to get to the remote host you're interested in reaching.
-Doing this will allow the multi-hop connection to work with rsync, even if
-both hosts prompt for a password -- this is because both ssh connections
-originate from the localhost, and thus both instances of ssh have access to
-the local tty to use for an out-of-band password prompt.
-
-<p>Here is an example config for your ~/.ssh/config file (substitute "target",
-"target_user", and "middle" as appropriate):
-
-<blockquote><pre>Host target
-  ProxyCommand nohup ssh middle nc -w1 %h %p
-  User target_user
-</pre></blockquote>
-
-<p>This proxy setup uses "ssh" to login to the firewall system ("middle") and
-uses "nc" (netcat) to connect to the target host ("target") using the default
-port number.  The use of "nohup" silences a warning at the end of the run, and
-the "-w1" option tells nc to shut down when the connection closes.
-
-<p>With this done, you can run a normal-looking rsync command to "target" that
-will run the proxy command to get through the firewall system:
-
-<blockquote><pre>rsync -av /src/ target:/dest/</pre></blockquote>
-
-<h4>Method 3 -- an alternate ssh method for those without nc (netcat)</h4>
-
-<p>Assuming you're using ssh as your remote shell, you can configure ssh to
-forward a local port through your middle system to the ssh port (22) on the
-target system.  This method does not require the use of nc (it uses only
-ssh to effect the extra hop), but otherwise it is similar to, but slightly
-less convenient than, method 2.
-
-<p>The first thing we need is an ssh configuration that will allow us to
-connect to the forwarded port as if we were connecting to the target
-system, and we need ssh to know what we're doing so that it doesn't
-complain about the host keys being wrong.  We can do this by adding this
-section to your ~/.ssh/config file (substitute "target" and "target_user"
-as appropriate, but leave "localhost" unchanged):
-
-<blockquote><pre>Host target
-  HostName localhost
-  Port 2222
-  HostKeyAlias target
-  User target_user
-</pre></blockquote>
-
-<p>Next, we need to enable the port forwarding:
-
-<blockquote><pre>ssh -fN -l middle_user -L 2222:target:22 middle</pre></blockquote>
-
-<p>What this does is cause a connection to port 2222 on the local system to
-get tunneled to the middle system and then turn into a connection to the
-target system's port 22.  The -N option tells ssh not to start a shell on
-the remote system, which works with modern ssh versions (you can run a
-sleep command if -N doesn't work).  The -f option tells ssh to put the
-command in the background after any password/passphrase prompts.
-
-<p>With this done, you could run a normal-looking rsync command to "target"
-that would use a connection to port 2222 on localhost automatically:
-
-<blockquote><pre>rsync -av target:/src/ /dest/</pre></blockquote>
-
-<p><b>Note:</b> starting an ssh tunnel allows anyone on the source system
-to connect to the localhost port 2222, not just you, but they'd still need
-to be able to login to the target system using their own credentials.
-
-<h4>Method 4 -- for using rsync in daemon-mode (requires nc)</h4>
-
-<p>Install and configure an rsync daemon on the target and use ssh and nc
-to send the socket data to the remote host.
-
-<blockquote><pre>RSYNC_CONNECT_PROG='ssh -l middle_user middle nc %H 873' \
-    rsync daemonuser@target::module/src/ /dest/</pre></blockquote>
-
-<p>(You can also export that variable into your environment if you want to
-perform a series of daemon rsync commands through the same middle host.)
-
-<p>This command takes advantage of the RSYNC_CONNECT_PROG environment
-variable, which tells rsync to pipe its socket data to an external program
-in place of making a direct socket connection.  The command specifed above
-uses ssh to run the nc (netcat) command on the middle host, which forwards
-all socket data to port 873 on the target host (%H).  The "%H" will be
-substituted with the target host from the rsync command as long as you're
-running rsync 3.0.0 or newer (you'll need to replace %H with the actual
-target hostname for earlier rsync versions, which makes the hostname
-specified in the rsync command superfluous).
-
-<h4>Method 5 -- for using rsync in daemon-mode (for those without nc)</h4>
-
-<p>Install and configure an rsync daemon on the target and use an ssh
-tunnel to reach the rsync sever.  This is similar to method 3, but it
-tunnels the daemon port for those that prefer to use an rsync daemon.
-
-<p>(Note that this method also works to tunnel a socket connection
-directly to a destination system if you use "localhost" as the target
-hostname and your destination system's name as the middle hostname.)
-
-<p>Installing the rsync daemon is beyond the scope of this document, but
-see the rsyncd.conf manpage for more information.  Keep in mind that you
-don't need to be root to run an rsync daemon as long as you don't use a
-protected port.
-
-<p>Once your rsync daemon is up and running, you build an ssh tunnel
-through your middle system like this:
-
-<blockquote><pre>ssh -fN -l middle_user -L 8873:target:873 middle</pre></blockquote>
-
-<p>What this does is cause a connection to port 8873 on the local system to
-turn into a connection from the middle system to the target system on port
-873.  (Port 873 is the normal port for an rsync daemon.) The -N option
-tells ssh not to start a shell on the remote system, which works with
-modern ssh versions (you can run a sleep command if -N doesn't work).  The
--f option tells ssh to put the command in the background after any
-password/passphrase prompts.
-
-<p>Now when an rsync command is executed with a daemon-mode command-line
-syntax to the local system, the conversation is directed to the target
-system.  For example:
-
-<blockquote><pre>rsync -av --port 8873 localhost::module/src/ dest/
-rsync -av rsync://localhost:8873/module/src/ dest/</pre></blockquote>
-
-<p><b>Note:</b> starting an ssh tunnel allows anyone on the source system
-to connect to the localhost port 8873, not just you, so you may want to
-enable username/password restrictions on your rsync daemon.
