+                            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
+  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
-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.
+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 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.
+  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 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.
+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.
 
-  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.
+  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.
 
-  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.
+  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.
 
-  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.
+  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.
-
-		    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".
+                       TERMS AND CONDITIONS
 
-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.
+  0. Definitions.
 
-  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.
+  "This License" refers to version 3 of the GNU General Public License.
 
-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.
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
 
-  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:
+  "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.
 
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
+  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.
 
-    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.
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
 
-    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.
+  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.
 
-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.
+  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.
 
-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.
+  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.
 
-  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:
+  1. Source Code.
 
-    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,
+  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.
 
-    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,
+  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.
 
-    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 "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 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.
+  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.
 
-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.
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
 
-  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.
+  The Corresponding Source for a work in source code form is that
+same work.
 
-  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
+  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.
 
-  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
+  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
-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.
+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.
 
-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.
+  13. Use with the GNU Affero General Public License.
 
-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.
+  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.
 
-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.

-specifies a version number of this License which applies to it and "any

+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published

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

-NEWS for rsync 2.6.4 (UNRELEASED)
-Protocol: 29 (changed)
-Changes since 2.6.3:
+NEWS for rsync 3.0.9 (23 Sep 2011)
+Protocol: 30 (unchanged)
+Changes since 3.0.8:
 
-  OUTPUT CHANGES:
-
-    - When rsync deletes a directory and outputs a verbose message about
-      it, it now appends a trailing slash to the name instead of (only
-      sometimes) outputting a preceding "directory " string.
-
-    - The --stats output will contain file-list time-statistics if both
-      sides are 2.6.4, or if the local side is 2.6.4 and the files are
-      being pushed (since the stats come from the sending side).
-      (Requires protocol 29 for a pull.)
-
-    - The "%o" (operation) log-format escape now has a third value (besides
-      "send" and "recv"):  "del." (with trailing dot to make it 4 chars).
-      This changes the way deletions are logged in the daemon's log file.
-
-    - When the --log-format option is combined with --verbose, rsync now
-      avoids outputting the name of the file twice in most circumstances.
-      As long as the --log-format item does not refer to any post-transfer
-      items (such as %b or %c), the --log-format message is output prior to
-      the transfer with --verbose being the equivalent of a --log-format of
-      '%n%L' (which outputs the name and any symlink info).  If the log
-      output must occur after the transfer to be complete, the only time
-      the name is also output prior to the transfer is when --progress was
-      specified (so that the name will precede the progress stats, and the
-      full --log-format output will come after).
-  
   BUG FIXES:
 
-    - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
-      was only treating it as a special token in an rsync include/exclude
-      file).
+    - Fix a crash bug in checksum scanning when --inplace is used.
 
-    - The combination of --verbose and --dry-run now mentions the full list
-      of changes that would be output without --dry-run.
+    - Fix a hang if a hard-linked file cannot be opened by the sender (e.g.
+      if it has no read permission).
 
-    - Avoid a mkdir warning when removing a directory in the destination
-      that already exists in the --backup-dir.
+    - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
 
-    - An OS that has a binary mode for its files (such as cygwin) needed
-      setmode(fd, O_BINARY) called on the temp-file we opened with
-      mkstemp().  (Fix derived from the cygwin's 2.6.3 rsync package.)
+    - Fix a memory leak in the xattr code.
 
-    - Fixed a potential hang when verbosity is high, the client side is
-      the sender, and the file-list is large.
+    - Fixed a bug with --delete-excluded when a filter merge file has a rule
+      that specifies a receiver-only side restriction.
 
-    - Fixed a potential protocol-corrupting bug where the generator could
-      merge a message from the receiver into the middle of a multiplexed
-      packet of data if only part of that data was written out to the
-      socket when we got the message from the generator.
+    - Fix a bug with the modifying of unwritable directories.
 
-    - We now check if the OS doesn't support using mknod() for creating
-      FIFOs and sockets, and compile-in using mkfifo() and socket() when
-      necessary.
+    - Fix --fake-super's interaction with --link-dest same-file comparisons.
 
-    - Fixed an off-by-one error in the handling of --max-delete=N.
+    - Fix the updating of the curr_dir buffer to avoid a duplicate slash.
 
-    - One place in the code wasn't checking if fork() failed.
+    - Fix the directory permissions on an implied dot-dir when using --relative
+      (e.g. /outside/path/././send/path).
 
-    - The "ignore nonreadable" daemon parameter used to erroneously affect
-      symlinks that pointed to a non-existent file.  This has been fixed.
+    - Fixed some too-long sleeping instances when using --bwlimit.
 
-    - If the OS does not have lchown() and a chown() of a symlink will
-      affect the referent of a symlink (as it should), we no longer try
-      to set the user and group of a symlink.
+    - Fixed when symlink ownership difference-checking gets compiled into
+      unchanged_attrs().
 
-    - The generator now properly runs the hard-link loop and the dir-time
-      rewriting loop after we're sure that the redo phase is complete.
+    - Improved the socket-error reporting when multiple protocols fail.
 
-    - When --backup was specified with --partial-dir=DIR (where DIR is a
-      relative path), the backup code was erroneously trying to backup a
-      file that was put into the partial-dir.
+    - Fixed a case where a socket error could reference just-freed memory.
 
-    - If a file gets resent in a single transfer and the --backup option is
-      enabled along with --inplace, rsync no longer performs a duplicate
-      backup (it used to overwrite the first backup with the failed file).
+    - Failing to use a password file that was specified on the command-line is
+      now a fatal error.
 
-    - One call to flush_write_file() was not being checked for an error.
+    - Fix the non-root updating of directories that don't have the read and/or
+      execute permission.
 
-    - The --no-relative option was not being sent from the client to a
-      server sender.
+    - Make daemon-excluded file errors more error-like.
 
-    - If an rsync daemon specified "dont compress = ..." for a file and the
-      client tried to specify --compress, the libz code was not handling a
-      compression level of 0 properly.  This could cause a transfer failure
-      if the block-size for a file was large enough (e.g. rsync might have
-      exited with an error for large files).
+    - Fix a compilation issue on older C compilers (due to a misplaced var
+      declaration).
 
-    - Fixed a bug that would sometimes surface when using --compress and
-      sending a file with a block-size larger than 64K (either manually
-      specified, or computed due to the file being really large).  Prior
-      versions of rsync would sometimes fail to decompress the data
-      properly, and thus the transferred file would fail its verification.
+    - Make configure avoid finding socketpair on cygwin.
 
-    - If a daemon can't open the specified log file (i.e. syslog is not
-      being used), die without crashing.  We also output an error about
-      the failure on stderr (which will only be seen if --no-detach was
-      specified).
+    - Avoid trying to reference SO_BROADCAST if the OS doesn't support it.
 
-    - A local transfer no longer duplicates all its include/exclude options
-      (since the forked process already has a copy of the exclude list,
-      there's no need to send them a set of duplicates).
+    - Fix some issues with the post-processing of the man pages.
 
-    - When --progress is specified, the output of items that the generator
-      is creating (e.g. dirs, symlinks) is now integrated into the progress
-      output without overlapping it.  (Requires protocol 29.)
+    - Fixed the user home-dir handling in the support/lsh script.
 
-    - When --timeout is specified, lulls that occur in the transfer while
-      the generator is doing work that does not generate socket traffic
-      (looking for changed files, deleting files, doing directory-time
-      touch-ups, etc.) will cause a new keep-alive packet to be sent that
-      should keep the transfer going as long as the generator continues to
-      make progress.  (Requires protocol 29.)
-
-    - The stat size of a device is not added to the total file size of the
-      items in the transfer since the size might be undefined on some OSes.
-
-    - Fixed a problem with refused-option messages sometimes not making it
-      back to the client side when a remote --files-from was in effect and
-      the daemon was the receiver.
-
-    - The --compare-dest option was not updating a file that differred in
-      (the preserved) attributes from the version in the compare-dest DIR.
-
-    - When rsync is copying files into a write-protected directory, fixed
-      the change-report output for the directory so that we don't report
-      an identical directory as changed.
-
-  ENHANCEMENTS:
-
-    - Rsync now supports popt's option aliases, which means that you can
-      use /etc/popt and/or ~/.popt to create your own option aliases.
-
-    - Added the --delete-during (--del) option which will delete files
-      from the receiving side incrementally as each directory in the
-      transfer is being processed.  This makes it more efficient than the
-      default, before-the-transfer behavior, which is now available as
-      --delete-before (and is still the default --delete-WHEN option that
-      will be chosen if --delete or --delete-excluded is specified without
-      a --delete-WHEN choice).  All the --del* options infer --delete, so
-      an rsync daemon that refuses "delete" will still refuse to allow any
-      file-deleting options.
-
-    - All the --delete-WHEN options are now more memory efficient:
-      Previously an entire duplicate set of file-list objects was created
-      on the receiving side for the entire destination hierarchy.  The new
-      algorithm only creates one directory of objects at a time (for files
-      inside the transfer).
-
-    - Added the --copy-dest option, which works like --link-dest except
-      that it copies identical files instead of hard-linking them.
-
-    - Added support for specifying multiple --compare-dest, --copy-dest, or
-      --link-dest options, but only of a single type. (Promoted from the
-      patches dir and enhanced.) (Requires protocol 29.)
-
-    - Added the --max-size option. (Promoted from the patches dir.)
-
-    - The daemon-mode options were separated from the normal rsync options
-      so that they can't be mixed together.  This makes it impossible to
-      start a daemon that had improper default option values that could
-      cause problems when a client connects (e.g. a hang or an abort).
-
-    - The --bwlimit option may now be used in combination with --daemon
-      to specify both a default value for the daemon side and a value
-      that cannot be exceeded by a user-specified --bwlimit option.
-
-    - Added the "port" parameter to the rsyncd.conf file. (Promoted from
-      the patches dir.)  Also added "address".  A command-line option
-      will take precedence over a config-file option, as expected.
-
-    - In _exit_cleanup(): when we are exiting with a partially-received
-      file, we now flush any data in the write-cache before closing the
-      partial file.
-
-    - The --inplace support was enhanced to work with --compare-dest,
-      --link-dest, and (the new) --copy-dest options. (Requires protocol
-      29.)
-
-    - Added the --dirs (-d) option for an easier way to copy directories
-      without recursion.
-
-    - Added the --list-only option, which is mainly a way for the client to
-      put the server into listing mode without needing to resort to any
-      internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
-      for a non-recursive listing).  This option is used automatically
-      (behind the scenes) when a modern rsync speaks to a modern daemon,
-      but may also be specified manually if you want to force the use of
-      the --list-only option over a remote-shell connection.
-
-    - Added the --omit-dir-times (-O) option, which will avoid updating
-      the modified time for directories when --times was specified.  This
-      option will avoid an extra pass through the file-list at the end of
-      the transfer (to tweak all the directory times), which can result in
-      an appreciable speedup for a really large transfer. (Promoted from
-      the patches dir.)
-
-    - Added the --filter (-f) option and its helper option, -F.  Filter
-      rules are an extension to the existing include/exclude handling
-      that also supports nested filter files as well as per-directory
-      filter files (like .cvsignore, but with full filter-rule parsing).
-      This new option was chosen in order to ensure that all existing
-      include/exclude processing remained 100% compatible with older
-      versions.  Protocol 29 is needed for full filter-rule support, but
-      backward-compatible rules work with earlier protocol versions.
-      (Promoted from the patches dir and enhanced.)
-
-    - Added the --delay-updates option that puts all updated files into
-      a temporary directory (by default ".~tmp~", but settable via the
-      --partial-dir=DIR option) until the end of the transfer.  This
-      makes the updates a little more atomic for a large transfer.
-
-    - If rsync is put into the background, any output from --progress is
-      reduced.
-
-    - Documented the "max verbosity" setting for rsyncd.conf.  (This
-      setting was added a couple releases ago, but left undocumented.)
-
-    - The sender and the generator now double-check the file-list index
-      they are given, and refuse to try to do a file transfer on a
-      non-file index (since that would indicate that something had gone
-      very wrong).
-
-    - Added the --itemize-changes (-i) option, which is a way to output a
-      more detailed list of what files changed in any way and how they
-      changed.  The effect is the same as specifying a --log-format of
-      "%i %n%L" (see the rsyncd.conf manpage).  Works with --dry-run too.
-
-    - Added the --fuzzy option, which attempts to find a basis file for a
-      file that is being created from scratch.  The current algorithm
-      only looks in the destination directory for the created file, but
-      it does attempt to find a match based on size/mod-time (in case the
-      file was renamed with no other changes) as well as based on a fuzzy
-      name-matching algorithm.  This option requires protocol 29 because
-      it needs the new file-sorting order.  (Promoted from patches dir
-      and enhanced.) (Requires protocol 29.)
-
-    - Added the --remove-sent-files option, which lets you move files
-      between systems.
-
-    - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
-      enclosed in '[' and ']' (e.g. "[::1]").  (We already allowed IPv6
-      literals in the rsync://HOST:PORT/PATH format.)
-
-    - When building under windows, the default for --daemon is now to
-      avoid detaching, requiring the new --detach option to force rsync
-      to detach.
-
-    - Improved the option descriptions in the --help text.
-
-  SUPPORT FILES:
-
-    - Added atomic-rsync to the support dir: a perl script that will
-      transfer some files using rsync, and then move the updated files into
-      place all at once at the end of the transfer.  Only works when
-      pulling, and uses --link-dest and a parallel hierarchy of files to
-      effect its update.
-
-    - Added mnt-excl to the support dir: a perl script that takes the
-      /proc/mounts file and translates it into a set of excludes that will
-      exclude all mount points (even mapped mounts to the same disk).  The
-      excludes are made relative to the specified source dir and properly
-      anchored.
-
-    - Added savetransfer.c to the support dir: a C program that can make
-      a copy of all the data that flows over the wire.  This lets you test
-      for data corruption (by saving the data on both the sending side and
-      the receiving side) or provides a way to help debug a protocol error.
-
-    - Added rrsync to the support dir: this is my version of Joe Smith's
-      restricted rsync perl script.  This helps to ensure that only certain
-      rsync commands can be run by an ssh invocation.
-
-  INTERNAL:
-
-    - Added better checking of the checksum-header values that come over
-      the socket.
-
-    - Merged a variety of file-deleting functions into a single function so
-      that it is easier to maintain.
-
-    - Improved the type of some variables (particularly blocksize vars) for
-      consistency and proper size.
-
-    - Got rid of the uint64 type (which we didn't need).
-
-    - Use a slightly more compatible set of core #include directives.
-
-    - Defined int32 in a way that ensures that the build dies if we can't
-      find a variable with at least 32 bits.
-
-    - The daemon's "read only" config item now sets an internal read_only
-      variable that makes extra sure that no write/delete calls on the
-      read-only side can succeed.
-
-  PROTOCOL DIFFERENCES FOR VERSION 29:
-
-    - A 16-bit flag-word is transmitted after every file-list index.  This
-      indicates what is changing between the sender and the receiver.  The
-      generator now transmits an index and a flag-word to indicate when
-      dirs and symlinks have changed (instead of producing a message),
-      which makes the outputting of the information more consistent and
-      less prone to screen corruption (because either the receiver or the
-      sender is now outputting all the file-change info).
-
-    - If a file is being hard-linked, the appropriate bit is enabled in
-      the flag-word and the name of the file that was linked immediately
-      follows in vstring format (see below).
-
-    - If a file is being transferred with an alternate-basis file, the
-      appropriate bit is enabled in the flag-word and a single-byte
-      follows, indicating what type of basis file was chosen.  If that
-      indicates that a fuzzy-match was selected, the name of the match
-      immediately follows in vstring format.  A vstring is a variable
-      length string that has its size written prior to the string, and
-      no terminating null.  If the string is from 1-127 bytes, the length
-      is a single byte.  If it is from 128-32767 bytes, the length is
-      written as ((len >> 8) | 0x80) followed by (len % 0x100).
-
-    - The sending of exclude names is done using filter-rule syntax.  This
-      means that all names have a prefixed rule indicator, even excludes
-      (which used to be sent as a bare pattern, when possible).  The -C
-      option will include the per-dir .cvsignore merge file in the list of
-      filter rules so it is positioned correctly (unlike in some older
-      transfer scenarios).
-
-    - Rsync sorts the filename list in a different way: it sorts the subdir
-      names after the non-subdir names for each dir's contents, and it
-      always puts a dir's contents immediately after the dir's name in the
-      list.  (Previously an item named "foo.txt" would sort in between
-      directory "foo/" and "foo/bar".)
-
-    - When talking to a protocol 29 rsync daemon, a list-only request
-      is able to note this before the options are sent over the wire and
-      the new --list-only option is included in the options.
-
-    - When the --stats bytes are sent over the wire (or stored in a batch),
-      they now include two elapsed-time values: one for how long it took to
-      build the file-list, and one for how long it took to send it over the
-      wire (each expressed in thousandths of a second).
-
-    - When --delete-excluded is specified with some filter excludes, a
-      client sender will now initiate a send of the filter rules to the
-      receiver (older protocols used to omit the sending of excludes in
-      this situation since there were no receiver-specific rules that
-      survived --delete-excluded back then).  Note that, as with all the
-      filter-list sending, only items that are significant to the other
-      side will actually be sent over the wire, so the filter-rule list
-      is often empty in this scenario.
-
-    - A protocol-29 batch file includes a bit for the setting of the --dirs
-      option.  Also, the shell script created by --write-batch will use the
-      --filter option instead of --exclude-from to capture any filter rules.
-
-    - An index equal to the file-list count is sent as a keep-alive packet
-      from the generator to the sender, which then forwards it on to the
-      receiver.  This normally invalid index is only a valid keep-alive
-      packet if the 16-bit flag-word that follows it contains a single bit
-      (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
-
-  BUILD CHANGES:
-
-    - Handle an operating system that use mkdev() in place of makedev().
-
-    - Improved configure to better handle cross-compiling.
+    - Some minor manpage improvements.

 WHAT IS RSYNC?
 --------------
 
-rsync is a replacement for scp/rcp that has many more features.
+Rsync is a fast and extraordinarily versatile file copying tool for
+both remote and local files.
 
-rsync uses the "rsync algorithm" which provides a very fast method for
-bringing remote files into sync. It does this by sending just the
+Rsync uses a delta-transfer 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.

 authentication and access control are available.

 %description
-Rsync uses a reliable algorithm to bring remote and host files into
-sync very quickly. Rsync is fast because it just sends the differences
-in the files over the network instead of sending the complete
-files. Rsync is often used as a very powerful mirroring process or
-just as a more capable replacement for the rcp command. A technical
-report which describes the rsync algorithm is included in this
-package.
+Rsync is a fast and extraordinarily versatile file copying tool.  It can
+copy locally, to/from another host over any remote shell, or to/from a
+remote rsync daemon.  It offers a large number of options that control
+every aspect of its behavior and permit very flexible specification of the
+set of files to be copied.  It is famous for its delta-transfer algorithm,
+which reduces the amount of data sent over the network by sending only the
+differences between the source files and the existing files in the
+destination.  Rsync is widely used for backups and mirroring and as an
+improved copy command for everyday use.

-* Mon Aug 25 1997 John A. Martin <jam@jamux.com>
-
-Built 1.6.3-2 after finding no rsync-1.6.3-1.src.rpm although there
-was an ftp://ftp.redhat.com/pub/contrib/alpha/rsync-1.6.3-1.alpha.rpm
-showing no packager nor signature but giving 
-"Source RPM: rsync-1.6.3-1.src.rpm".
-
-Changes from 1.6.2-1 packaging: added '$RPM_OPT_FLAGS' to make, strip
-to '%build', removed '%prefix'.
-

 usually contains site information and any legal notices. The default

-rsync server. You may use any standard syslog facility name which is
-defined on your system. Common names are auth, authpriv, cron, daemon,

-for each module in tt(rsyncd.conf).
-
-dit(bf(use chroot)) If "use chroot" is true, the rsync server will chroot
-to the "path" before starting the file transfer with the client.  This has
-the advantage of extra protection against possible implementation security
-holes, but it has the disadvantages of requiring super-user privileges, 
-of not being able to follow symbolic links that are either absolute or outside
-of the new root path, and of complicating the preservation of usernames and groups
-(see below).  When "use chroot" is false, for security reasons,
-symlinks may only be relative paths pointing to other files within the root
-path, and leading slashes are removed from most absolute paths (options
-such as bf(--backup-dir), bf(--compare-dest), etc. interpret an absolute path as
-rooted in the module's "path" dir, just as if chroot was specified).
-The default for "use chroot" is true.
-
-In order to preserve usernames and groupnames, rsync needs to be able to
-use the standard library functions for looking up names and IDs (i.e.
-getpwuid(), getgrgid(), getpwname(), and getgrnam()).  This means a
-process in the chroot namespace will need to have access to the resources
-used by these library functions (traditionally /etc/passwd and
-/etc/group).  If these resources are not available, rsync will only be
-able to copy the IDs, just as if the bf(--numeric-ids) option had been
-specified.
-
-Note that you are free to setup user/group information in the chroot area
-differently from your normal system.  For example, you could abbreviate
-the list of users and groups.  Also, you can protect this information from
-being downloaded/uploaded by adding an exclude rule to the rsync.conf file
-(e.g. "exclude = /etc/**").  Note that having the exclusion affect uploads
-is a relatively new feature in rsync, so make sure your server is running
-at least 2.6.3 to effect this.  Also note that it is safest to exclude a
-directory and all its contents combining the rule "/some/dir/" with the
-rule "/some/dir/**" just to be sure that rsync will not allow deeper
-access to some of the excluded files inside the directory (rsync tries to

+name contains whitespace, each internal sequence of whitespace will be
+changed into a single space, while leading or trailing whitespace will be
+discarded.
+
+startdit()
+
+dit(bf(comment)) This parameter specifies a description string
+that is displayed next to the module name when clients obtain a list
+of available modules. The default is no comment.
+
+dit(bf(path)) This parameter specifies the directory in the daemon's
+filesystem to make available in this module.  You must specify this parameter
+for each module in tt(rsyncd.conf).
+
+It is fine if the path includes internal spaces -- they will be retained
+verbatim (which means that you shouldn't try to escape them).  If your final
+directory has a trailing space (and this is somehow not something you wish to
+fix), append a trailing slash to the path to avoid losing the trailing
+whitespace.
+
+dit(bf(use chroot)) If "use chroot" is true, the rsync daemon will chroot
+to the "path" before starting the file transfer with the client.  This has
+the advantage of extra protection against possible implementation security
+holes, but it has the disadvantages of requiring super-user privileges,
+of not being able to follow symbolic links that are either absolute or outside
+of the new root path, and of complicating the preservation of users and groups
+by name (see below).
+
+As an additional safety feature, you can specify a dot-dir in the module's
+"path" to indicate the point where the chroot should occur.  This allows rsync
+to run in a chroot with a non-"/" path for the top of the transfer hierarchy.
+Doing this guards against unintended library loading (since those absolute
+paths will not be inside the transfer hierarchy unless you have used an unwise
+pathname), and lets you setup libraries for the chroot that are outside of the
+transfer.  For example, specifying "/var/rsync/./module1" will chroot to the
+"/var/rsync" directory and set the inside-chroot path to "/module1".  If you
+had omitted the dot-dir, the chroot would have used the whole path, and the
+inside-chroot path would have been "/".
+
+When "use chroot" is false or the inside-chroot path is not "/", rsync will:
+(1) munge symlinks by
+default for security reasons (see "munge symlinks" for a way to turn this
+off, but only if you trust your users), (2) substitute leading slashes in
+absolute paths with the module's path (so that options such as
+bf(--backup-dir), bf(--compare-dest), etc. interpret an absolute path as
+rooted in the module's "path" dir), and (3) trim ".." path elements from
+args if rsync believes they would escape the module hierarchy.
+The default for "use chroot" is true, and is the safer choice (especially
+if the module is not read-only).
+
+When this parameter is enabled, rsync will not attempt to map users and groups
+by name (by default), but instead copy IDs as though bf(--numeric-ids) had
+been specified.  In order to enable name-mapping, rsync needs to be able to
+use the standard library functions for looking up names and IDs (i.e.
+code(getpwuid()), code(getgrgid()), code(getpwname()), and code(getgrnam())).
+This means the rsync
+process in the chroot hierarchy will need to have access to the resources
+used by these library functions (traditionally /etc/passwd and
+/etc/group, but perhaps additional dynamic libraries as well).
+
+If you copy the necessary resources into the module's chroot area, you
+should protect them through your OS's normal user/group or ACL settings (to
+prevent the rsync module's user from being able to change them), and then
+hide them from the user's view via "exclude" (see how in the discussion of
+that parameter).  At that point it will be safe to enable the mapping of users
+and groups by name using the "numeric ids" daemon parameter (see below).
+
+Note also that you are free to setup custom user/group information in the
+chroot area that is different from your normal system.  For example, you
+could abbreviate the list of users and groups.
+
+dit(bf(numeric ids)) Enabling this parameter disables the mapping
+of users and groups by name for the current daemon module.  This prevents
+the daemon from trying to load any user/group-related files or libraries.
+This enabling makes the transfer behave as if the client had passed
+the bf(--numeric-ids) command-line option.  By default, this parameter is
+enabled for chroot modules and disabled for non-chroot modules.
+
+A chroot-enabled module should not have this parameter enabled unless you've
+taken steps to ensure that the module has the necessary resources it needs
+to translate names, and that it is not possible for a user to change those
+resources.
+
+dit(bf(munge symlinks)) This parameter tells rsync to modify
+all incoming symlinks in a way that makes them unusable but recoverable
+(see below).  This should help protect your files from user trickery when
+your daemon module is writable.  The default is disabled when "use chroot"
+is on and the inside-chroot path is "/", otherwise it is enabled.
+
+If you disable this parameter on a daemon that is not read-only, there
+are tricks that a user can play with uploaded symlinks to access
+daemon-excluded items (if your module has any), and, if "use chroot"
+is off, rsync can even be tricked into showing or changing data that
+is outside the module's path (as access-permissions allow).
+
+The way rsync disables the use of symlinks is to prefix each one with
+the string "/rsyncd-munged/".  This prevents the links from being used
+as long as that directory does not exist.  When this parameter is enabled,
+rsync will refuse to run if that path is a directory or a symlink to
+a directory.  When using the "munge symlinks" parameter in a chroot area
+that has an inside-chroot path of "/", you should add "/rsyncd-munged/"
+to the exclude setting for the module so that
+a user can't try to create it.
+
+Note:  rsync makes no attempt to verify that any pre-existing symlinks in
+the module's hierarchy are as safe as you want them to be (unless, of
+course, it just copied in the whole hierarchy).  If you setup an rsync
+daemon on a new area or locally add symlinks, you can manually protect your
+symlinks from being abused by prefixing "/rsyncd-munged/" to the start of
+every symlink's value.  There is a perl script in the support directory
+of the source code named "munge-symlinks" that can be used to add or remove
+this prefix from your symlinks.
+
+When this parameter is disabled on a writable module and "use chroot" is off
+(or the inside-chroot path is not "/"),
+incoming symlinks will be modified to drop a leading slash and to remove ".."
+path elements that rsync believes will allow a symlink to escape the module's
+hierarchy.  There are tricky ways to work around this, though, so you had
+better trust your users if you choose this combination of parameters.
+
+dit(bf(charset)) This specifies the name of the character set in which the
+module's filenames are stored.  If the client uses an bf(--iconv) option,
+the daemon will use the value of the "charset" parameter regardless of the
+character set the client actually passed.  This allows the daemon to
+support charset conversion in a chroot module without extra files in the
+chroot area, and also ensures that name-translation is done in a consistent
+manner.  If the "charset" parameter is not set, the bf(--iconv) option is
+refused, just as if "iconv" had been specified via "refuse options".
+
+If you wish to force users to always use bf(--iconv) for a particular
+module, add "no-iconv" to the "refuse options" parameter.  Keep in mind
+that this will restrict access to your module to very new rsync clients.
+
+dit(bf(max connections)) This parameter allows you to
 specify the maximum number of simultaneous connections you will allow.
 Any clients connecting when the maximum has been reached will receive a
-message telling them to try later.  The default is 0 which means no limit.
-See also the "lock file" option.
+message telling them to try later.  The default is 0, which means no limit.
+A negative value disables the module.
+See also the "lock file" parameter.
 
-dit(bf(max verbosity)) The "max verbosity" option allows you to control
+dit(bf(log file)) When the "log file" parameter is set to a non-empty
+string, the rsync daemon will log messages to the indicated file rather
+than using syslog. This is particularly useful on systems (such as AIX)
+where code(syslog()) doesn't work for chrooted programs.  The file is
+opened before code(chroot()) is called, allowing it to be placed outside
+the transfer.  If this value is set on a per-module basis instead of
+globally, the global log will still contain any authorization failures
+or config-file error messages.
+
+If the daemon fails to open the specified file, it will fall back to
+using syslog and output an error about the failure.  (Note that the
+failure to open the specified log file used to be a fatal error.)
+
+dit(bf(syslog facility)) This parameter allows you to
+specify the syslog facility name to use when logging messages from the
+rsync daemon. You may use any standard syslog facility name which is
+defined on your system. Common names are auth, authpriv, cron, daemon,
+ftp, kern, lpr, mail, news, security, syslog, user, uucp, local0,
+local1, local2, local3, local4, local5, local6 and local7. The default
+is daemon.  This setting has no effect if the "log file" setting is a
+non-empty string (either set in the per-modules settings, or inherited
+from the global settings).
+
+dit(bf(max verbosity)) This parameter allows you to control
 the maximum amount of verbose information that you'll allow the daemon to
 generate (since the information goes into the log file). The default is 1,
 which allows the client to request one level of verbosity.
 
-dit(bf(lock file)) The "lock file" option specifies the file to use to
-support the "max connections" option. The rsync server uses record
+dit(bf(lock file)) This parameter specifies the file to use to
+support the "max connections" parameter. The rsync daemon uses record
 locking on this file to ensure that the max connections limit is not

+exceeded for the modules sharing the lock file.
 The default is tt(/var/run/rsyncd.lock).
 
-dit(bf(read only)) The "read only" option determines whether clients
+dit(bf(read only)) This parameter determines whether clients
 will be able to upload files or not. If "read only" is true then any
 attempted uploads will fail. If "read only" is false then uploads will
-be possible if file permissions on the server allow them. The default
+be possible if file permissions on the daemon side allow them. The default
 is for all modules to be read only.
 
-dit(bf(write only)) The "write only" option determines whether clients
+dit(bf(write only)) This parameter determines whether clients
 will be able to download files or not. If "write only" is true then any
 attempted downloads will fail. If "write only" is false then downloads
-will be possible if file permissions on the server allow them.  The
-default is for this option to be disabled.
+will be possible if file permissions on the daemon side allow them.  The
+default is for this parameter to be disabled.
 
-dit(bf(list)) The "list" option determines if this module should be
+dit(bf(list)) This parameter determines if this module should be
 listed when the client asks for a listing of available modules. By
 setting this to false you can create hidden modules. The default is
 for modules to be listable.
 
-dit(bf(uid)) The "uid" option specifies the user name or user ID that
+dit(bf(uid)) This parameter specifies the user name or user ID that
 file transfers to and from that module should take place as when the daemon
-was run as root. In combination with the "gid" option this determines what
+was run as root. In combination with the "gid" parameter this determines what
 file permissions are available. The default is uid -2, which is normally
 the user "nobody".
 
-dit(bf(gid)) The "gid" option specifies the group name or group ID that
+dit(bf(gid)) This parameter specifies the group name or group ID that
 file transfers to and from that module should take place as when the daemon
-was run as root. This complements the "uid" option. The default is gid -2,
+was run as root. This complements the "uid" parameter. The default is gid -2,
 which is normally the group "nobody".
 
-dit(bf(filter)) The "filter" option allows you to specify a space-separated
-list of filter rules that the server will not allow to be read or written.
-This is only superficially equivalent to the client specifying these
-patterns with the bf(--filter) option.  Only one "filter" option may be
-specified, but it may contain as many rules as you like, including
-merge-file rules.  Note that per-directory merge-file rules do not provide
-as much protection as global rules, but they can be used to make bf(--delete)
-work better when a client downloads the server's files (if the per-dir
-merge files are included in the transfer).
+dit(bf(fake super)) Setting "fake super = yes" for a module causes the
+daemon side to behave as if the bf(--fake-super) command-line option had
+been specified.  This allows the full attributes of a file to be stored
+without having to have the daemon actually running as root.
 
-dit(bf(exclude)) The "exclude" option allows you to specify a
-space-separated list of patterns that the server will not allow to be read
-or written.  This is only superficially equivalent to the client
-specifying these patterns with the bf(--exclude) option.  Only one "exclude"
-option may be specified, but you can use "-" and "+" before patterns to
-specify exclude/include.
+dit(bf(filter)) The daemon has its own filter chain that determines what files
+it will let the client access.  This chain is not sent to the client and is
+independent of any filters the client may have specified.  Files excluded by
+the daemon filter chain (bf(daemon-excluded) files) are treated as non-existent
+if the client tries to pull them, are skipped with an error message if the
+client tries to push them (triggering exit code 23), and are never deleted from
+the module.  You can use daemon filters to prevent clients from downloading or
+tampering with private administrative files, such as files you may add to
+support uid/gid name translations.
 
-Because this exclude list is not passed to the client it only applies on
-the server: that is, it excludes files received by a client when receiving
-from a server and files deleted on a server when sending to a server, but
-it doesn't exclude files from being deleted on a client when receiving
-from a server.  
+The daemon filter chain is built from the "filter", "include from", "include",
+"exclude from", and "exclude" parameters, in that order of priority.  Anchored
+patterns are anchored at the root of the module.  To prevent access to an
+entire subtree, for example, "/secret", you em(must) exclude everything in the
+subtree; the easiest way to do this is with a triple-star pattern like
+"/secret/***".
 
-dit(bf(exclude from)) The "exclude from" option specifies a filename
-on the server that contains exclude patterns, one per line.
-This is only superficially equivalent
-to the client specifying the bf(--exclude-from) option with an equivalent file.
-See the "exclude" option above.
+The "filter" parameter takes a space-separated list of daemon filter rules,
+though it is smart enough to know not to split a token at an internal space in
+a rule (e.g. "- /foo  - /bar" is parsed as two rules).  You may specify one or
+more merge-file rules using the normal syntax.  Only one "filter" parameter can
+apply to a given module in the config file, so put all the rules you want in a
+single parameter.  Note that per-directory merge-file rules do not provide as
+much protection as global rules, but they can be used to make bf(--delete) work
+better during a client download operation if the per-dir merge files are
+included in the transfer and the client requests that they be used.
 
-dit(bf(include)) The "include" option allows you to specify a
-space-separated list of patterns which rsync should not exclude. This is
-only superficially equivalent to the client specifying these patterns with
-the bf(--include) option because it applies only on the server.  This is
-useful as it allows you to build up quite complex exclude/include rules.
-Only one "include" option may be specified, but you can use "+" and "-"
-before patterns to switch include/exclude.  See the "exclude" option
-above.
+dit(bf(exclude)) This parameter takes a space-separated list of daemon
+exclude patterns.  As with the client bf(--exclude) option, patterns can be
+qualified with "- " or "+ " to explicitly indicate exclude/include.  Only one
+"exclude" parameter can apply to a given module.  See the "filter" parameter
+for a description of how excluded files affect the daemon.
 
-dit(bf(include from)) The "include from" option specifies a filename
-on the server that contains include patterns, one per line. This is
-only superficially equivalent to the client specifying the
-bf(--include-from) option with a equivalent file.
-See the "exclude" option above.
+dit(bf(include)) Use an "include" to override the effects of the "exclude"
+parameter.  Only one "include" parameter can apply to a given module.  See the
+"filter" parameter for a description of how excluded files affect the daemon.
 
-dit(bf(auth users)) The "auth users" option specifies a comma and
+dit(bf(exclude from)) This parameter specifies the name of a file
+on the daemon that contains daemon exclude patterns, one per line.  Only one
+"exclude from" parameter can apply to a given module; if you have multiple
+exclude-from files, you can specify them as a merge file in the "filter"
+parameter.  See the "filter" parameter for a description of how excluded files
+affect the daemon.
+
+dit(bf(include from)) Analogue of "exclude from" for a file of daemon include
+patterns.  Only one "include from" parameter can apply to a given module.  See
+the "filter" parameter for a description of how excluded files affect the
+daemon.
+
+dit(bf(incoming chmod)) This parameter allows you to specify a set of
+comma-separated chmod strings that will affect the permissions of all
+incoming files (files that are being received by the daemon).  These
+changes happen after all other permission calculations, and this will
+even override destination-default and/or existing permissions when the
+client does not specify bf(--perms).
+See the description of the bf(--chmod) rsync option and the bf(chmod)(1)
+manpage for information on the format of this string.
+
+dit(bf(outgoing chmod)) This parameter allows you to specify a set of
+comma-separated chmod strings that will affect the permissions of all
+outgoing files (files that are being sent out from the daemon).  These
+changes happen first, making the sent permissions appear to be different
+than those stored in the filesystem itself.  For instance, you could
+disable group write permissions on the server while having it appear to
+be on to the clients.
+See the description of the bf(--chmod) rsync option and the bf(chmod)(1)
+manpage for information on the format of this string.
+
+dit(bf(auth users)) This parameter specifies a comma and
 space-separated list of usernames that will be allowed to connect to
 this module. The usernames do not need to exist on the local
 system. The usernames may also contain shell wildcard characters. If
 "auth users" is set then the client will be challenged to supply a
 username and password to connect to the module. A challenge response
 authentication protocol is used for this exchange. The plain text

-manpagesection(RUNNING AN RSYNC SERVER OVER A REMOTE SHELL PROGRAM)
-
-If rsync is run with both the bf(--daemon) and bf(--rsh) (bf(-e)) options, it will
-spawn an rsync daemon using a remote shell connection.  Several
-configuration options will not be available unless the remote user is
-root (e.g. chroot, setuid/setgid, etc.).  There is no need to configure
-inetd or the services map to include the rsync server port if you run an
-rsync server only via a remote shell program.
-
-ADVANCED: To run an rsync server out of a single-use ssh key, use the
-"command=em(COMMAND)" syntax in the remote user's authorized_keys entry,
-where command would be
-
-quote(tt(rsync --server --daemon .))
-
-NOTE: rsync's argument parsing expects the trailing ".", so make sure
-that it's there.  If you want to use an rsyncd.conf(5)-style
-configuration file other than the default, you can added a
-bf(--config) option to the em(command):
-
-quote(tt(rsync --server --daemon --config=em(file) .))
-
-Note that the "--server" here is the internal option that rsync uses to
-run the remote version of rsync that it communicates with, and thus you
-should not be using the bf(--server) option under normal circumstances.
