  Everyone is permitted to copy and distribute verbatim copies
  of this license document, but changing it is not allowed.
 
-                            Preamble
+			    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
+  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
-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.
+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 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.
+  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 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.
+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.
 
-  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.
+  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.
 
-  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.
+  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.
 
-  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.
+  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.
-
-                       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
+
+		    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.)
+
+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.
+
+  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.
 
-  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
+  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 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.
+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.
 
-  13. Use with the GNU Affero General Public License.
+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.
 
-  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.
+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.
 
-  14. Revised Versions of this License.
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  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.

-the GNU General Public License from time to time.  Such new versions will
+  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 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.

+this 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.
+  10. If you wish to incorporate parts of the Program into other free

+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.

-To build and install rsync:
-
-    $ ./configure
-    $ make
-    # make install
-
-You may set the installation directory and other parameters by options
-to ./configure.  To see them, use:
-
-    $ ./configure --help
-
-Configure tries to figure out if the local system uses group "nobody" or
-"nogroup" by looking in the /etc/group file.  (This is only used for the
-default group of an rsync daemon, which attempts to run with "nobody"
-user and group permissions.)  You can change the default user and group
-for the daemon by editing the NOBODY_USER and NOBODY_GROUP defines in
-config.h, or just override them in your /etc/rsyncd.conf file.
-
-As of 2.4.7, rsync uses Eric Troan's popt option-parsing library.  A
-cut-down copy of a recent release is included in the rsync distribution,
-and will be used if there is no popt library on your build host, or if
-the --with-included-popt option is passed to ./configure.
-
-If you configure using --enable-maintainer-mode, then rsync will try
-to pop up an xterm on DISPLAY=:0 if it crashes.  You might find this
-useful, but it should be turned off for production builds.
-
-MAKE COMPATIBILITY
-------------------
-
-Note that Makefile.in has a rule that uses a wildcard in a prerequisite.  If
-your make has a problem with this rule, you will see an error like this:
-
-    Don't know how to make ./*.c
-
-You can change the "proto.h-tstamp" target in Makefile.in to list all the *.c
-filenames explicitly in order to avoid this issue.
-
-RPM NOTES
----------
-
-Under packaging you will find .spec files for several distributions.
-The .spec file in packaging/lsb can be used for Linux systems that
-adhere to the Linux Standards Base (e.g., RedHat and others).

-
-IBM AIX NOTES
--------------
-
-IBM AIX has a largefile problem with mkstemp.  See IBM PR-51921.

+WHAT IS RSYNC?
+--------------
+
+rsync is a replacement for rcp that has many more features.
+
+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.
+At first glance this may seem impossible because the calculation of
+diffs between two files normally requires local access to both
+files. 
+
+A technical report describing the rsync algorithm is included with
+this package. 
+
+
+USAGE
+-----
+
+Basically you use rsync just like rcp, but rsync has many additional options.
+
+Here is a brief description of rsync usage:
+
+Usage: rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
+  or   rsync [OPTION]... [USER@]HOST:SRC DEST
+  or   rsync [OPTION]... SRC [SRC]... DEST
+  or   rsync [OPTION]... [USER@]HOST::SRC [DEST]
+  or   rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
+  or   rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
+SRC on single-colon remote HOST will be expanded by remote shell
+SRC on server remote HOST may contain shell wildcards or multiple
+  sources separated by space as long as they have same top-level
+
+Options
+ -v, --verbose               increase verbosity
+ -q, --quiet                 decrease verbosity

+ -p, --perms                 preserve permissions
+ -o, --owner                 preserve owner (root only)
+ -g, --group                 preserve group
+ -D, --devices               preserve devices (root only)
+ -t, --times                 preserve times
+ -S, --sparse                handle sparse files efficiently
+ -n, --dry-run               show what would have been transferred
+ -W, --whole-file            copy whole files, no incremental checks
+ -x, --one-file-system       don't cross filesystem boundaries
+ -B, --block-size=SIZE       checksum blocking size (default 700)
+ -e, --rsh=COMMAND           specify rsh replacement
+     --rsync-path=PATH       specify path to rsync on the remote machine

+ -h, --help                  show this help screen
+
+
+
+SETUP
+-----
+
+Rsync normally uses rsh or ssh for communication.  It does not need to
+be setuid and requires no special privileges for installation.  You
+must, however, have a working rsh or ssh system. Using ssh is
+recommended for its security features.
+
+Alternatively, rsync can run in `daemon' mode, listening on a socket.
+This is generally used for public file distribution, although
+authentication and access control are available.
+
+To install rsync, first run the "configure" script. This will create a
+Makefile and config.h appropriate for your system. Then type
+"make". 
+
+Note that on some systems you will have to force configure not to use
+gcc because gcc may not support some features (such as 64 bit file
+offsets) that your system may support. Set the environment variable CC
+to the name of your native compiler before running configure in this
+case. 
+
+Once built put a copy of rsync in your search path on the local and
+remote systems (or use "make install"). That's it!
+
+RSYNC SERVERS
+-------------
+
+rsync can also talk to "rsync servers" which can provide anonymous or
+authenticated rsync. See the rsyncd.conf(5) man page for details on how
+to setup a rsync server. See the rsync(1) man page for info on how to
+connect to a rsync server.
+
+
+MAILING LIST
+------------
+
+There is a mailing list for the discussion of rsync and its
+applications. It is open to anyone to join. I will announce new
+versions on this list. 
+
+To join the mailing list see the web page at http://lists.samba.org/
+
+To send mail to everyone on the list send it to rsync@samba.org
+
+
+BUG REPORTS
+-----------
+
+If you have web access then please look at
+http://rsync.samba.org/rsync/ 
+
+This will give you access to the bug tracking system used by the
+developers of rsync and will allow you to look at other bug reports or
+submit a new bug report.
+
+If you don't have web access then mail bug reports to rsync@samba.org.
+
+
+CVS TREE
+--------
+
+If you want to get the very latest version of rsync direct from the
+source code repository then you can use anonymous cvs. You will need a
+recent version of cvs then use the following commands:
+
+	cvs -d :pserver:cvs@pserver.samba.org:/cvsroot login
+	Password: cvs
+
+	cvs -d :pserver:cvs@pserver.samba.org:/cvsroot co rsync
+
+Look at the cvs documentation, or http://samba.org/cvs.html, for more
+details.

-  Perhaps allow supplementary groups to be specified in rsyncd.conf;
-  then make the first one the primary gid and all the rest be
-  supplementary gids.
+  Traverse just one directory at a time.  Tridge says it's possible.

+  At the moment rsync reads the whole file list into memory at the

+  network access as much as we could.
 
 
-Handling IPv6 on old machines
+Handling duplicate names
 
-  The KAME IPv6 patch is nice in theory but has proved a bit of a
-  nightmare in practice.  The basic idea of their patch is that rsync
-  is rewritten to use the new getaddrinfo()/getnameinfo() interface,
-  rather than gethostbyname()/gethostbyaddr() as in rsync 2.4.6.
-  Systems that don't have the new interface are handled by providing
-  our own implementation in lib/, which is selectively linked in.
+  We need to be careful of duplicate names getting into the file list.
+  See clean_flist().  This could happen if multiple arguments include
+  the same file.  Bad.
 
-  The problem with this is that it is really hard to get right on
-  platforms that have a half-working implementation, so redefining
-  these functions clashes with system headers, and leaving them out
-  breaks.  This affects at least OSF/1, RedHat 5, and Cobalt, which
-  are moderately important.
+  I think duplicates are only a problem if they're both flowing
+  through the pipeline at the same time.  For example we might have
+  updated the first occurrence after reading the checksums for the
+  second.  So possibly we just need to make sure that we don't have
+  both in the pipeline at the same time.  
 
-  Perhaps the simplest solution would be to have two different files
-  implementing the same interface, and choose either the new or the
-  old API.  This is probably necessary for systems that e.g. have
-  IPv6, but gethostbyaddr() can't handle it.  The Linux manpage claims
-  this is currently the case.
+  Possibly if we did one directory at a time that would be sufficient.
 
-  In fact, our internal sockets interface (things like
-  open_socket_out(), etc) is much narrower than the getaddrinfo()
-  interface, and so probably simpler to get right.  In addition, the
-  old code is known to work well on old machines.
+  Alternatively we could pre-process the arguments to make sure no
+  duplicates will ever be inserted.  There could be some bad cases
+  when we're collapsing symlinks.
 
-  We could drop the rather large lib/getaddrinfo files.
+  We could have a hash table.
 
-                      --          --
+  The root of the problem is that we do not want more than one file
+  list entry referring to the same file.  At first glance there are
+  several ways this could happen: symlinks, hardlinks, and repeated
+  names on the command line.
+
+  If names are repeated on the command line, they may be present in
+  different forms, perhaps by traversing directory paths in different
+  ways, traversing paths including symlinks.  Also we need to allow
+  for expansion of globs by rsync.
+
+  At the moment, clean_flist() requires having the entire file list in
+  memory.  Duplicate names are detected just by a string comparison.
+
+  We don't need to worry about hard links causing duplicates because
+  files are never updated in place.  Similarly for symlinks.
+
+  I think even if we're using a different symlink mode we don't need
+  to worry.
+
+  Unless we're really clever this will introduce a protocol
+  incompatibility, so we need to be able to accept the old format as
+  well.
 
 
-Other IPv6 stuff
-  
+Memory accounting
+
+  At exit, show how much memory was used for the file list, etc.
+
+  Also we do a wierd exponential-growth allocation in flist.c.  I'm
+  not sure this makes sense with modern mallocs.  At any rate it will
+  make us allocate a huge amount of memory for large file lists.
+
+  We can try using the GNU/SVID/XPG mallinfo() function to get some
+  heap statistics.
+
+
+Hard-link handling
+
+  At the moment hardlink handling is very expensive, so it's off by
+  default.  It does not need to be so.  
+
+  Since most of the solutions are rather intertwined with the file
+  list it is probably better to fix that first, although fixing
+  hardlinks is possibly simpler.
+
+  We can rule out hardlinked directories since they will probably
+  screw us up in all kinds of ways.  They simply should not be used.
+
+  At the moment rsync only cares about hardlinks to regular files.  I
+  guess you could also use them for sockets, devices and other beasts,
+  but I have not seen them.
+
+  When trying to reproduce hard links, we only need to worry about
+  files that have more than one name (nlinks>1 && !S_ISDIR). 
+
+  The basic point of this is to discover alternate names that refer to
+  the same file.  All operations, including creating the file and
+  writing modifications to it need only to be done for the first name.
+  For all later names, we just create the link and then leave it
+  alone.
+
+  If hard links are to be preserved:
+
+    Before the generator/receiver fork, the list of files is received
+    from the sender (recv_file_list), and a table for detecting hard
+    links is built.
+
+    The generator looks for hard links within the file list and does
+    not send checksums for them, though it does send other metadata.
+
+    The sender sends the device number and inode with file entries, so
+    that files are uniquely identified.
+
+    The receiver goes through and creates hard links (do_hard_links)
+    after all data has been written, but before directory permissions
+    are set.
+
+  At the moment device and inum are sent as 4-byte integers, which
+  will probably cause problems on large filesystems.  On Linux the
+  kernel uses 64-bit ino_t's internally, and people will soon have
+  filesystems big enough to use them.  We ought to follow NFS4 in
+  using 64-bit device and inode identification, perhaps with a
+  protocol version bump.
+
+  Once we've seen all the names for a particular file, we no longer
+  need to think about it and we can deallocate the memory.
+
+  We can also have the case where there are links to a file that are
+  not in the tree being transferred.  There's nothing we can do about
+  that.  Because we rename the destination into place after writing,
+  any hardlinks to the old file are always going to be orphaned.  In
+  fact that is almost necessary because otherwise we'd get really
+  confused if we were generating checksums for one name of a file and
+  modifying another.
+
+  At the moment the code seems to make a whole second copy of the file
+  list, which seems unnecessary.
+
+  We should have a test case that exercises hard links.  Since it
+  might be hard to compare ./tls output where the inodes change we
+  might need a little program to check whether several names refer to
+  the same file.

-Handling duplicate names
-
-  Some folks would like rsync to be deterministic in how it handles
-  duplicate names that come from mering multiple source directories
-  into a single destination directory; e.g. the last name wins.  We
-  could do this by switching our sort algorithm to one that will
-  guarantee that the names won't be reordered.  Alternately, we could
-  assign an ever-increasing number to each item as we insert it into
-  the list and then make sure that we leave the largest number when
-  cleaning the file list (see clean_flist()).  Another solution would
-  be to add a hash table, and thus never put any duplicate names into
-  the file list (and bump the protocol to handle this).

-    - avoids people breaking rsync by trying to do this themselves and
-      messing up
-
-  Should we ship zlib for systems that don't have it, or require
-  people to install it separately?
-
-  Apparently this will make us incompatible with versions of rsync
-  that use the patched version of rsync.  Probably the simplest way to
-  do this is to just disable gzip (with a warning) when talking to old
-  versions.

-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.

-	<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)

- lookup3.c, by Bob Jenkins, May 2006, Public Domain.
-
- These are functions for producing 32-bit hashes for hash table lookup.
- hash_word(), hashlittle(), hashlittle2(), hashbig(), mix(), and final()
- are externally useful functions.  Routines to test the hash are included
- if SELF_TEST is defined.  You can use this free for any purpose.  It's in
- the public domain.  It has no warranty.
-
- You probably want to use hashlittle().  hashlittle() and hashbig()
- hash byte arrays.  hashlittle() is is faster than hashbig() on
- little-endian machines.  Intel and AMD are little-endian machines.
- On second thought, you probably want hashlittle2(), which is identical to
- hashlittle() except it returns two 32-bit hashes for the price of one.
- You could implement hashbig2() if you wanted but I haven't bothered here.
-
- If you want to find a hash of, say, exactly 7 integers, do
-   a = i1;  b = i2;  c = i3;
-   mix(a,b,c);
-   a += i4; b += i5; c += i6;
-   mix(a,b,c);
-   a += i7;
-   final(a,b,c);
- then use c as the hash value.  If you have a variable length array of
- 4-byte integers to hash, use hash_word().  If you have a byte array (like
- a character string), use hashlittle().  If you have several byte arrays, or
- a mix of things, see the comments above hashlittle().
-
- Why is this so big?  I read 12 bytes at a time into 3 4-byte integers,
- then mix those integers.  This is fast (you can do a lot more thorough
- mixing with 12*3 instructions on 3 integers than you can with 3 instructions
- on 1 byte), but shoehorning those bytes into integers efficiently is messy.

- mix -- mix 3 32-bit values reversibly.
-
- This is reversible, so any information in (a,b,c) before mix() is
- still in (a,b,c) after mix().
-
- If four pairs of (a,b,c) inputs are run through mix(), or through
- mix() in reverse, there are at least 32 bits of the output that
- are sometimes the same for one pair and different for another pair.
- This was tested for:
- * pairs that differed by one bit, by two bits, in any combination
-   of top bits of (a,b,c), or in any combination of bottom bits of
-   (a,b,c).
- * "differ" is defined as +, -, ^, or ~^.  For + and -, I transformed
-   the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
-   is commonly produced by subtraction) look like a single 1-bit
-   difference.
- * the base values were pseudorandom, all zero but one bit set, or
-   all zero plus a counter that starts at zero.
-
- Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that
- satisfy this are
-     4  6  8 16 19  4
-     9 15  3 18 27 15
-    14  9  3  7 17  3
- Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing
- for "differ" defined as + with a one-bit base and a two-bit delta.  I
- used http://burtleburtle.net/bob/hash/avalanche.html to choose
- the operations, constants, and arrangements of the variables.
-
- This does not achieve avalanche.  There are input bits of (a,b,c)
- that fail to affect some output bits of (a,b,c), especially of a.  The
- most thoroughly mixed value is c, but it doesn't really even achieve
- avalanche in c.
-
- This allows some parallelism.  Read-after-writes are good at doubling
- the number of bits affected, so the goal of mixing pulls in the opposite
- direction as the goal of parallelism.  I did what I could.  Rotates
- seem to cost as much as shifts on every machine I could lay my hands
- on, and rotates are much kinder to the top and bottom bits, so I used
- rotates.

-   val2    : IN: can be any 4-byte value OUT: second 32 bit hash.
- Returns a 32-bit value.  Every bit of the key affects every bit of
- the return value.  Two keys differing by one or two bits will have
- totally different hash values.  Note that the return value is better
- mixed than val2, so use that first.
-
- The best hash table sizes are powers of 2.  There is no need to do
- mod a prime (mod is sooo slow!).  If you need less than 32 bits,
- use a bitmask.  For example, if you need only 10 bits, do
-   h = (h & hashmask(10));
- In which case, the hash table should have hashsize(10) elements.
-
- If you are hashing n strings (uint8_t **)k, do it like this:

- * x86-64 optimized assembler MD5 implementation
- *
- * Author: Marc Bevand, 2004
- *
- * This code was placed in the public domain by the author. The original
- * publication can be found at:
- *
- * https://www.zorinaq.com/papers/md5-amd64.html
- */
-/*
- * No modifications were made aside from changing the function and file names.
- * The MD5_CTX structure as expected here (from OpenSSL) is binary compatible
- * with the md_context used by rsync, for the fields accessed.
- *
- * Benchmarks (in MB/s)            C     ASM
- * - Intel Atom D2700            302     334
- * - Intel i7-7700hq             351     376
- * - AMD ThreadRipper 2950x      728     784
- *
- * The original code was also incorporated into OpenSSL. It has since been
- * modified there. Those changes have not been made here due to licensing
- * incompatibilities. Benchmarks of those changes on the above CPUs did not
- * show any significant difference in performance, though.

-.SH DESCRIPTION
-.P
-The pool allocation routines use
-.B malloc()
-for underlying memory management.
-What allocation pools do is cause memory within a given pool
-to be allocated in large contiguous blocks
-(called extents) that will be reusable when freed.  Unlike
-.BR malloc() ,
-the allocations are not managed individually.
-Instead, each extent tracks the total free memory within the
-extent.  Each extent can either be used to allocate memory
-or to manage the freeing of memory within that extent.
-When an extent has less free memory than a given
-allocation request, the current extent ceases to be used
-for allocation.  See also the
-.B pool_boundary()
-function.
-.P
-This form of memory management is suited to large numbers of small
-related allocations that are held for a while
-and then freed as a group.
-Because the
-underlying allocations are done in large contiguous extents,
-when an extent is freed, it can release a large enough
-contiguous block of memory to allow the memory to be returned
-to the OS for use by whatever program needs it.
-You can allocate from one or more memory pools and/or
-.B malloc()
-all at the same time without interfering with how pools work.
-.P
-.B pool_create()
-Creates an allocation pool for subsequent calls to the pool
-allocation functions.
-When an extent is created for allocations it will be
-.I size 
-bytes.
-Allocations from the pool have their sizes rounded up to a
-multiple of
-.I quantum
-bytes in length.
-Specifying
-.B 0
-for
-.I quantum
-will produce a quantum that should meet maximal alignment
-on most platforms.
-Unless
-.B POOL_NO_QALIGN
-is set in the
-.IR flags ,
-allocations will be aligned to addresses that are a
-multiple of
-.IR quantum .
-A
-.B NULL
-may be specified for the
-.I bomb
-function pointer if it is not needed.  (See the
-.B pool_alloc()
-function for how it is used.)
-If
-.B POOL_CLEAR
-is set in the
-.IR flags ,
-all allocations from the pool will be initialized to zeros.
-If either
-.B POOL_PREPEND
-or
-.B POOL_INTERN
-is specified in the
-.IR flags ,
-each extent's data structure will be allocated at the start of the
-.IR size -length
-buffer (rather than as a separate, non-pool allocation), with the
-former extending the
-.I size
-to hold the structure, and the latter subtracting the structure's
-length from the indicated
-.IR size .
-.P
-.B pool_destroy()
-destroys an allocation
-.I pool
-and frees all its associated memory.
-.P
-.B pool_alloc()
-allocates
-.I size
-bytes from the specified
-.IR pool .
-If
-.I size
-is
-.BR 0 ,
-.I quantum
-bytes will be allocated.
-If the pool has been created without
-.BR POOL_NO_QALIGN ,
-every chunk of memory that is returned will be suitably aligned.
-You can use this with the default
-.I quantum
-size to ensure that all memory can store a variable of any type.
-If the requested memory cannot be allocated, the
-.I bomb()
-function will be called with
-.I msg
-as its sole argument (if the function was defined at the time
-the pool was created), and then a
-.B NULL
-address is returned (assuming that the bomb function didn't exit).
-.P
-.B pool_free()
-frees
-.I size
-bytes pointed to by an
-.I addr
-that was previously allocated in the specified
-.IR pool .
-If
-.I size
-is
-.BR 0 ,
-.I quantum
-bytes will be freed.
-The memory freed within an extent will not be reusable until
-all of the memory in that extent has been freed with one
-exception: the most recent pool allocation may be freed back
-into the pool prior to making any further allocations.
-If enough free calls are made to indicate that an extent has no
-remaining allocated objects (as computed by the total freed size for
-an extent), its memory will be completely freed back to the system.
-If
-.I addr
-is
-.BR NULL ,
-no memory will be freed, but subsequent allocations will come
-from a new extent.
-.P
-.B pool_free_old()
-takes a boundary
-.I addr
-value that was returned by
-.B pool_boundary()
-and frees up any extents in the
-.I pool
-that have data allocated from that point backward in time.
-NOTE: you must NOT mix calls to both
-.B pool_free
-and
-.B pool_free_old
-on the same pool!
-.P
-.B pool_boundary()
-asks for a boundary value that can be sent to 
-.B pool_free_old()
-at a later time to free up all memory allocated prior to a particular
-moment in time.
-If the extent that holds the boundary point has allocations from after the
-boundary point, it will not be freed until a future
-.B pool_free_old()
-call encompasses the entirety of the extent's data.
-If
-.I len
-is non-zero, the call will also check if the active extent has at least
-that much free memory available in it, and if not, it will mark the
-extent as inactive, forcing a new extent to be used for future allocations.
-(You can specify -1 for
-.I len
-if you want to force a new extent to start.)
-.P
-.B pool_talloc()
-is a macro that takes a
-.I type
-and a
-.I count
-instead of a
-.IR size .
-It casts the return value to the correct pointer type.
-.P
-.B pool_tfree
-is a macro that calls
-.B pool_free
-on memory that was allocated by
-.BR pool_talloc() .
-.SH RETURN VALUE
-.B pool_create()
-returns a pointer to
-.BR "struct alloc_pool" .
-.P
-.B pool_alloc()
-and
-.B pool_talloc()
-return pointers to the allocated memory,
-or NULL if the request fails.
-The return type of
-.B pool_alloc()
-will normally require casting to the desired type but
-.B pool_talloc()
-will returns a pointer of the requested
-.IR type .
-.P
-.B pool_boundary()
-returns a pointer that should only be used in a call to
-.BR pool_free_old() .
-.P
-.BR pool_free() ,
-.BR pool_free_old() ,
-.B pool_tfree()
-and
-.B pool_destroy()
-return no value.

-# This script takes a manpage written in markdown and turns it into an html web
-# page and a nroff man page.  The input file must have the name of the program
-# and the section in this format: NAME.NUM.md.  The output files are written
-# into the current directory named NAME.NUM.html and NAME.NUM.  The input
-# format has one extra extension: if a numbered list starts at 0, it is turned
-# into a description list. The dl's dt tag is taken from the contents of the
-# first tag inside the li, which is usually a p, code, or strong tag.  The
-# cmarkgfm or commonmark lib is used to transforms the input file into html.
-# The html.parser is used as a state machine that both tweaks the html and
-# outputs the nroff data based on the html tags.
