+Git v1.7.11 Release Notes
+=========================
+
+Updates since v1.7.10
+---------------------
+
+UI, Workflows & Features
+
+ * A new mode for push, "simple", which is a cross between "current"
+   and "upstream", has been introduced. "git push" without any refspec
+   will push the current branch out to the same name at the remote
+   repository only when it is set to track the branch with the same
+   name over there.  The plan is to make this mode the new default
+   value when push.default is not configured.
+
+ * A couple of commands learned the "--column" option to produce
+   columnar output.
+
+ * A third-party tool "git subtree" is distributed in contrib/
+
+ * Error messages given when @{u} is used for a branch without its
+   upstream configured have been clatified.
+
+ * Even with "-q"uiet option, "checkout" used to report setting up
+   tracking.  Also "branch" learned the "-q"uiet option to squelch
+   informational message.
+
+ * Your build platform may support hardlinks but you may prefer not to
+   use them, e.g. when installing to DESTDIR to make a tarball and
+   untarring on a filesystem that has poor support for hardlinks.
+   There is a Makefile option NO_INSTALL_HARDLINKS for you.
+
+ * The smart-http backend used to always override GIT_COMMITTER_*
+   variables with REMOTE_USER and REMOTE_ADDR, but these variables are
+   now preserved when set.
+
+ * "git am" learned the "--include" option, which is an opposite of
+   existing the "--exclude" option.
+
+ * When "git am -3" needs to fall back to an application to a
+   synthesized preimage followed by a 3-way merge, the paths that
+   needed such treatment are now reported to the end user, so that the
+   result in them can be eyeballed with extra care.
+
+ * The output from "diff/log --stat" used to always allocate 4 columns
+   to show the number of modified lines, but not anymore.
+
+ * "git difftool" learned the "--dir-diff" option to spawn external
+   diff tools that can compare two directory hierarchies at a time
+   after populating two temporary directories, instead of running an
+   instance of the external tool once per a file pair.
+
+ * The "fmt-merge-msg" command learns to list the primary contributors
+   involved in the side topic you are merging.
+
+ * "git rebase" learned to optionally keep commits that do not
+   introduce any change in the original history.
+
+ * "git push --recurse-submodules" learned to optionally look into the
+   histories of submodules bound to the superproject and push them
+   out.
+
+ * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
+   based on the commit date.
+
+ * "gitweb" learned to highlight the patch it outputs even more.
+
+Foreign Interface
+
+ * "git svn" used to die with unwanted SIGPIPE when talking with HTTP
+   server that uses keep-alive.
+
+ * "git svn" learned to use platform specific authentication
+   providers, e.g. gnome-keyring, kwallet, etc.
+
+ * "git p4" has been moved out of contrib/ area and has seen more work
+   on importing labels as tags from (and exporting tags as labels to)
+   p4.
+
+Performance and Internal Implementation (please report possible regressions)
+
+ * An experimental "version 4" format of the index file has been
+   introduced to reduce on-disk footprint and I/O overhead.
+
+ * "git archive" learned to produce its output without reading the
+   blob object it writes out in memory in its entirety.
+
+ * "git index-pack" that runs when fetching or pushing objects to
+   complete the packfile on the receiving end learned to use multiple
+   threads to do its job when available.
+
+ * The code to compute hash values for lines used by the internal diff
+   engine was optimized on little-endian machines, using the same
+   trick the kernel folks came up with.
+
+ * "git apply" had some memory leaks plugged.
+
+ * Setting up a revision traversal with many starting points was
+   inefficient as these were placed in a date-order priority queue
+   one-by-one.  Now they are collected in the queue unordered first,
+   and sorted immediately before getting used.
+
+ * More lower-level commands learned to use the streaming API to read
+   from the object store without keeping everything in core.
+
+ * Because "sh" on the user's PATH may be utterly broken on some
+   systems, run-command API now uses SHELL_PATH, not /bin/sh, when
+   spawning an external command (not applicable to Windows port).
+
+ * The API to iterate over refs/ hierarchy has been tweaked to allow
+   walking only a subset of it more efficiently.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.10
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * "git status --porcelain" ignored "--branch" option by mistake.  The
+   output for "git status --branch -z" was also incorrect and did not
+   terminate the record for the current branch name with NUL as asked.
+   (merge d4a6bf1 jk/maint-status-porcelain-z-b later to maint).
+
+ * "git diff --stat" used to fully count a binary file with modified
+   execution bits whose contents is unmodified, which was not quite
+   right.

+Responses To Commands
+---------------------
+New objects written by fast-import are not available immediately.
+Most fast-import commands have no visible effect until the next
+checkpoint (or completion).  The frontend can send commands to
+fill fast-import's input pipe without worrying about how quickly
+they will take effect, which improves performance by simplifying
+scheduling.
+
+For some frontends, though, it is useful to be able to read back
+data from the current repository as it is being updated (for
+example when the source material describes objects in terms of
+patches to be applied to previously imported objects).  This can
+be accomplished by connecting the frontend and fast-import via
+bidirectional pipes:
+
+====
+	mkfifo fast-import-output
+	frontend <fast-import-output |
+	git fast-import >fast-import-output
+====
+
+A frontend set up this way can use `progress`, `ls`, and `cat-blob`
+commands to read information from the import in progress.
+
+To avoid deadlock, such frontends must completely consume any
+pending output from `progress`, `ls`, and `cat-blob` before
+performing writes to fast-import that might block.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    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.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+HOW TO INSTALL git-subtree
+==========================
+
+First, build from the top source directory.
+
+Then, in contrib/subtree, run:
+
+  make
+  make install
+  make install-doc
+
+If you used configure to do the main build the git-subtree build will
+pick up those settings.  If not, you will likely have to provide a
+value for prefix:
+
+  make prefix=<some dir>
+  make prefix=<some dir> install
+  make prefix=<some dir> install-doc
+
+To run tests first copy git-subtree to the main build area so the
+newly-built git can find it:
+
+  cp git-subtree ../..
+
+Then:
+
+  make test

+
+DESCRIPTION
+-----------
+Subtrees allow subprojects to be included within a subdirectory
+of the main project, optionally including the subproject's
+entire history.
+
+For example, you could include the source code for a library
+as a subdirectory of your application.
+
+Subtrees are not to be confused with submodules, which are meant for
+the same task. Unlike submodules, subtrees do not need any special
+constructions (like .gitmodule files or gitlinks) be present in
+your repository, and do not force end-users of your
+repository to do anything special or to understand how subtrees
+work. A subtree is just a subdirectory that can be
+committed to, branched, and merged along with your project in
+any way you want.
+
+They are also not to be confused with using the subtree merge
+strategy. The main difference is that, besides merging
+the other project as a subdirectory, you can also extract the
+entire history of a subdirectory from your project and make it
+into a standalone project. Unlike the subtree merge strategy
+you can alternate back and forth between these
+two operations. If the standalone library gets updated, you can
+automatically merge the changes into your project; if you
+update the library inside your project, you can "split" the
+changes back out again and merge them back into the library
+project.
+
+For example, if a library you made for one application ends up being
+useful elsewhere, you can extract its entire history and publish
+that as its own git repository, without accidentally
+intermingling the history of your application project.
+
+[TIP]
+In order to keep your commit messages clean, we recommend that
+people split their commits between the subtrees and the main
+project as much as possible.  That is, if you make a change that
+affects both the library and the main application, commit it in
+two pieces.  That way, when you split the library commits out
+later, their descriptions will still make sense.  But if this
+isn't important to you, it's not *necessary*.  git subtree will
+simply leave out the non-library-related parts of the commit
+when it splits it out into the subproject later.
+
+
+COMMANDS
+--------
+add::
+	Create the <prefix> subtree by importing its contents
+	from the given <refspec> or <repository> and remote <refspec>.
+	A new commit is created	automatically, joining the imported
+	project's history with your own.  With '--squash', imports
+	only a single commit from the subproject, rather than its
+	entire history.
+
+merge::
+	Merge recent changes up to <commit> into the <prefix>
+	subtree.  As with normal 'git merge', this doesn't
+	remove your own local changes; it just merges those
+	changes into the latest <commit>.  With '--squash',
+	creates only one commit that contains all the changes,
+	rather than merging in the entire history.
+
+	If you use '--squash', the merge direction doesn't
+	always have to be forward; you can use this command to
+	go back in time from v2.5 to v2.4, for example.  If your
+	merge introduces a conflict, you can resolve it in the
+	usual ways.
+	
+pull::
+	Exactly like 'merge', but parallels 'git pull' in that
+	it fetches the given commit from the specified remote
+	repository.
+	
+push::
+	Does a 'split' (see above) using the <prefix> supplied
+	and then does a 'git push' to push the result to the 
+	repository and refspec. This can be used to push your
+	subtree to different branches of the remote repository.
+
+split::
+	Extract a new, synthetic project history from the
+	history of the <prefix> subtree.  The new history
+	includes only the commits (including merges) that
+	affected <prefix>, and each of those commits now has the
+	contents of <prefix> at the root of the project instead
+	of in a subdirectory.  Thus, the newly created history
+	is suitable for export as a separate git repository.
+	
+	After splitting successfully, a single commit id is
+	printed to stdout.  This corresponds to the HEAD of the
+	newly created tree, which you can manipulate however you
+	want.
+	
+	Repeated splits of exactly the same history are
+	guaranteed to be identical (ie. to produce the same
+	commit ids).  Because of this, if you add new commits
+	and then re-split, the new commits will be attached as
+	commits on top of the history you generated last time,
+	so 'git merge' and friends will work as expected.
+	
+	Note that if you use '--squash' when you merge, you
+	should usually not just '--rejoin' when you split.
+
+
+OPTIONS
+-------
+-q::
+--quiet::
+	Suppress unnecessary output messages on stderr.
+
+-d::
+--debug::
+	Produce even more unnecessary output messages on stderr.
+
+-P <prefix>::
+--prefix=<prefix>::
+	Specify the path in the repository to the subtree you
+	want to manipulate.  This option is mandatory
+	for all commands.
+
+-m <message>::
+--message=<message>::
+	This option is only valid for add, merge and pull (unsure).
+	Specify <message> as the commit message for the merge commit.
+
+
+OPTIONS FOR add, merge, push, pull
+----------------------------------
+--squash::
+	This option is only valid for add, merge, push and pull
+	commands.
+
+	Instead of merging the entire history from the subtree
+	project, produce only a single commit that contains all
+	the differences you want to merge, and then merge that
+	new commit into your project.
+	
+	Using this option helps to reduce log clutter. People
+	rarely want to see every change that happened between
+	v1.0 and v1.1 of the library they're using, since none of the
+	interim versions were ever included in their application.
+	
+	Using '--squash' also helps avoid problems when the same
+	subproject is included multiple times in the same
+	project, or is removed and then re-added.  In such a
+	case, it doesn't make sense to combine the histories
+	anyway, since it's unclear which part of the history
+	belongs to which subtree.
+	
+	Furthermore, with '--squash', you can switch back and
+	forth between different versions of a subtree, rather
+	than strictly forward.  'git subtree merge --squash'
+	always adjusts the subtree to match the exactly
+	specified commit, even if getting to that commit would
+	require undoing some changes that were added earlier.
+	
+	Whether or not you use '--squash', changes made in your
+	local repository remain intact and can be later split
+	and send upstream to the subproject.
+
+
+OPTIONS FOR split
+-----------------
+--annotate=<annotation>::
+	This option is only valid for the split command.
+
+	When generating synthetic history, add <annotation> as a
+	prefix to each commit message.  Since we're creating new
+	commits with the same commit message, but possibly
+	different content, from the original commits, this can help
+	to differentiate them and avoid confusion.
+	
+	Whenever you split, you need to use the same
+	<annotation>, or else you don't have a guarantee that
+	the new re-created history will be identical to the old
+	one.  That will prevent merging from working correctly. 
+	git subtree tries to make it work anyway, particularly
+	if you use --rejoin, but it may not always be effective.
+
+-b <branch>::
+--branch=<branch>::
+	This option is only valid for the split command.
+
+	After generating the synthetic history, create a new
+	branch called <branch> that contains the new history. 
+	This is suitable for immediate pushing upstream. 
+	<branch> must not already exist.
+
+--ignore-joins::
+	This option is only valid for the split command.
+
+	If you use '--rejoin', git subtree attempts to optimize
+	its history reconstruction to generate only the new
+	commits since the last '--rejoin'.  '--ignore-join'
+	disables this behaviour, forcing it to regenerate the
+	entire history.  In a large project, this can take a
+	long time.
+
+--onto=<onto>::
+	This option is only valid for the split command.
+
+	If your subtree was originally imported using something
+	other than git subtree, its history may not match what
+	git subtree is expecting.  In that case, you can specify
+	the commit id <onto> that corresponds to the first
+	revision of the subproject's history that was imported
+	into your project, and git subtree will attempt to build
+	its history from there.
+	
+	If you used 'git subtree add', you should never need
+	this option.
+
+--rejoin::
+	This option is only valid for the split command.
+
+	After splitting, merge the newly created synthetic
+	history back into your main project.  That way, future
+	splits can search only the part of history that has
+	been added since the most recent --rejoin.
+	
+	If your split commits end up merged into the upstream
+	subproject, and then you want to get the latest upstream
+	version, this will allow git's merge algorithm to more
+	intelligently avoid conflicts (since it knows these
+	synthetic commits are already part of the upstream
+	repository).
+	
+	Unfortunately, using this option results in 'git log'
+	showing an extra copy of every new commit that was
+	created (the original, and the synthetic one).
+	
+	If you do all your merges with '--squash', don't use
+	'--rejoin' when you split, because you don't want the
+	subproject's history to be part of your project anyway.
+
+
+EXAMPLE 1. Add command
+----------------------
+Let's assume that you have a local repository that you would like
+to add an external vendor library to. In this case we will add the
+git-subtree repository as a subdirectory of your already existing
+git-extensions repository in ~/git-extensions/:
+
+	$ git subtree add --prefix=git-subtree --squash \
+		git://github.com/apenwarr/git-subtree.git master
+
+'master' needs to be a valid remote ref and can be a different branch
+name
+
+You can omit the --squash flag, but doing so will increase the number
+of commits that are incldued in your local repository.
+
+We now have a ~/git-extensions/git-subtree directory containing code
+from the master branch of git://github.com/apenwarr/git-subtree.git
+in our git-extensions repository.
+
+EXAMPLE 2. Extract a subtree using commit, merge and pull
+---------------------------------------------------------
+Let's use the repository for the git source code as an example.
+First, get your own copy of the git.git repository:
+
+	$ git clone git://git.kernel.org/pub/scm/git/git.git test-git
+	$ cd test-git
+
+gitweb (commit 1130ef3) was merged into git as of commit
+0a8f4f0, after which it was no longer maintained separately. 
+But imagine it had been maintained separately, and we wanted to
+extract git's changes to gitweb since that time, to share with
+the upstream.  You could do this:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' \
+        	0a8f4f0^.. --onto=1130ef3 --rejoin \
+        	--branch gitweb-latest
+        $ gitk gitweb-latest
+        $ git push git@github.com:whatever/gitweb.git gitweb-latest:master
+        
+(We use '0a8f4f0^..' because that means "all the changes from
+0a8f4f0 to the current version, including 0a8f4f0 itself.")
+
+If gitweb had originally been merged using 'git subtree add' (or
+a previous split had already been done with --rejoin specified)
+then you can do all your splits without having to remember any
+weird commit ids:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' --rejoin \
+		--branch gitweb-latest2
+
+And you can merge changes back in from the upstream project just
+as easily:
+
+	$ git subtree pull --prefix=gitweb \
+		git@github.com:whatever/gitweb.git master
+
+Or, using '--squash', you can actually rewind to an earlier
+version of gitweb:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest~10
+
+Then make some changes:
+
+	$ date >gitweb/myfile
+	$ git add gitweb/myfile
+	$ git commit -m 'created myfile'
+
+And fast forward again:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest
+
+And notice that your change is still intact:
+	
+	$ ls -l gitweb/myfile
+
+And you can split it out and look at your changes versus
+the standard gitweb:
+
+	git log gitweb-latest..$(git subtree split --prefix=gitweb)
+
+EXAMPLE 3. Extract a subtree using branch
+-----------------------------------------
+Suppose you have a source directory with many files and
+subdirectories, and you want to extract the lib directory to its own
+git project. Here's a short way to do it:
+
+First, make the new repository wherever you want:
+
+	$ <go to the new location>
+	$ git init --bare
+
+Back in your original directory:
+
+	$ git subtree split --prefix=lib --annotate="(split)" -b split
+
+Then push the new branch onto the new empty repository:
+
+	$ git push <new-repo> split:master

+
+	--prefix doesn't force the subtree correctly in merge/pull:
+	"-s subtree" should be given an explicit subtree option?
+		There doesn't seem to be a way to do this.  We'd have to
+		patch git-merge-subtree.  Ugh.
+		(but we could avoid this problem by generating squashes with
+		exactly the right subtree structure, rather than using
+		subtree merge...)
+
+	add a 'push' subcommand to parallel 'pull'
+	
+	add a 'log' subcommand to see what's new in a subtree?
+
+	add to-submodule and from-submodule commands
+
+	automated tests for --squash stuff
+
+	"add" command non-obviously requires a commitid; would be easier if
+		it had a "pull" sort of mode instead
+
+	"pull" and "merge" commands should fail if you've never merged
+		that --prefix before
+		
+	docs should provide an example of "add"
+	
+	note that the initial split doesn't *have* to have a commitid
+		specified... that's just an optimization
+
+	if you try to add (or maybe merge?) with an invalid commitid, you
+		get a misleading "prefix must end with /" message from
+		one of the other git tools that git-subtree calls.  Should
+		detect this situation and print the *real* problem.
+	
+	"pull --squash" should do fetch-synthesize-merge, but instead just
+		does "pull" directly, which doesn't work at all.
+
+	make a 'force-update' that does what 'add' does even if the subtree
+		already exists.  That way we can help people who imported
+		subtrees "incorrectly" (eg. by just copying in the files) in
+		the past.
+
+	guess --prefix automatically if possible based on pwd
+
+	make a 'git subtree grafts' that automatically expands --squash'd
+		commits so you can see the full history if you want it.

-test_description='external credential helper tests'
+test_description='external credential helper tests
+
+This is a tool for authors of external helper tools to sanity-check
+their helpers. If you have written the "git-credential-foo" helper,
+you check it with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo t0303-credential-external.sh
+
+This assumes that your helper is capable of both storing and
+retrieving credentials (some helpers may be read-only, and they will
+fail these tests).
+
+Please note that the individual tests do not verify all of the
+preconditions themselves, but rather build on each other. A failing
+test means that tests later in the sequence can return false "OK"
+results.
+
+If your helper supports time-based expiration with a configurable
+timeout, you can test that feature with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo \
+       GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
+       t0303-credential-external.sh
+
+If your helper requires additional setup before the tests are started,
+you can set GIT_TEST_CREDENTIAL_HELPER_SETUP to a sequence of shell
+commands.
