+Git v1.7.11 Release Notes
+=========================
+
+Updates since v1.7.10
+---------------------
+
+UI, Workflows & Features
+
+ * A third-party tool "git subtree" is distributed in contrib/
+
+ * Even with "-q"uiet option, "checkout" used to report setting up
+ tracking. Also "branch" learned the "-q"uiet option to squelch
+ informational message.
+
+ * 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 "fmt-merge-msg" command learns to list the primary contributors
+ involved in the side topic you are merging.
+
+ * The cases "git push" fails due to non-ff can be broken into three
+ categories; each case is given a separate advise message.
+
+ * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
+ based on the commit date.
+
+Foreign Interface
+
+
+Performance
+
+
+Internal Implementation (please report possible regressions)
+
+ * Minor memory leak during unpack_trees (hence "merge" and "checkout"
+ to check out another branch) has been plugged.
+
+ * 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).
+
+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).
+
+ * When PATH contains an unreadable directory, alias expansion code
+ did not kick in, and failed with an error that said "git-subcmd"
+ was not found.
+ (merge 38f865c jk/run-command-eacces later to maint).
+
+ * The 'push to upstream' implementation was broken in some corner
+ cases. "git push $there" without refspec, when the current branch
+ is set to push to a remote different from $there, used to push to
+ $there using the upstream information to a remote unreleated to
+ $there.
+ (merge 135dade jc/push-upstream-sanity later to maint).
+
+ * "git clean -d -f" (not "-d -f -f") is supposed to protect nested
+ working trees of independent git repositories that exist in the
+ current project working tree from getting removed, but the
+ protection applied only to such working trees that are at the
+ top-level of the current project by mistake.
+ (merge ae2f203 jc/maint-clean-nested-worktree-in-subdir later to maint).
+
+ * Rename detection logic used to match two empty files as renames
+ during merge-recursive, leading unnatural mismerges.
+ (merge 4f7cb99 jk/diff-no-rename-empty later to maint).
+
+ * An age-old corner case bug in combine diff (only triggered with -U0
+ and the hunk at the beginning of the file needs to be shown) has
+ been fixed.
+ (merge e5e9b56 rs/combine-diff-zero-context-at-the-beginning later to maint).
+
+ * When "git commit --template F" errors out because the user did not
+ touch the message, it claimed that it aborts due to "empty
+ message", which was utterly wrong.
+ (merge 1f08c2c jc/commit-unedited-template later to maint).
+
+ * "git add -p" is not designed to deal with unmerged paths but did
+ not exclude them and tried to apply funny patches only to fail.
+ (merge 4066bd6 jk/add-p-skip-conflicts later to maint).
+
+ * "git commit --author=$name" did not tell the name that was being
+ recorded in the resulting commit to hooks, even though it does do
+ so when the end user overrode the authorship via the
+ "GIT_AUTHOR_NAME" environment variable.
+ (merge 7dfe8ad jc/commit-hook-authorship later to maint).
+
+ * The regexp configured with diff.wordregex was incorrectly reused
+ across files.
+ (merge 6440d34 tr/maint-word-diff-regex-sticky later to maint).
+
+ * Running "notes merge --commit" failed to perform correctly when run
+ from any directory inside $GIT_DIR/. When "notes merge" stops with
+ conflicts, $GIT_DIR/NOTES_MERGE_WORKTREE is the place a user edits
+ to resolve it.
+ (merge dabba59 jh/notes-merge-in-git-dir-worktree later to maint).

pushNonFastForward::
- Advice shown when linkgit:git-push[1] refuses
- non-fast-forward refs.
+ Set this variable to 'false' if you want to disable
+ 'pushNonFFCurrent', 'pushNonFFDefault', and
+ 'pushNonFFMatching' simultaneously.
+ pushNonFFCurrent::
+ Advice shown when linkgit:git-push[1] fails due to a
+ non-fast-forward update to the current branch.
+ pushNonFFDefault::
+ Advice to set 'push.default' to 'upstream' or 'current'
+ when you ran linkgit:git-push[1] and pushed 'matching
+ refs' by default (i.e. you did not provide an explicit
+ refspec, and no 'push.default' configuration was set)
+ and it resulted in a non-fast-forward error.
+ pushNonFFMatching::
+ Advice shown when you ran linkgit:git-push[1] and pushed
+ 'matching refs' explicitly (i.e. you used ':', or
+ specified a refspec that isn't your current branch) and
+ it resulted in a non-fast-forward error.
statusHints::
Directions on how to stage/unstage/add shown in the
output of linkgit:git-status[1] and the template shown
[--3way] [--interactive] [--committer-date-is-author-date]
[--ignore-date] [--ignore-space-change | --ignore-whitespace]
[--whitespace=<option>] [-C<n>] [-p<n>] [--directory=<dir>]
- [--exclude=<path>] [--reject] [-q | --quiet]
+ [--exclude=<path>] [--include=<path>] [--reject] [-q | --quiet]
[--scissors | --no-scissors]
[(<mbox> | <Maildir>)...]
'git am' (--continue | --skip | --abort)
-p<n>::
--directory=<dir>::
--exclude=<path>::
+--include=<path>::
--reject::
These flags are passed to the 'git apply' (see linkgit:git-apply[1])
program that applies
relationship to upstream branch (if any). If given twice, print
the name of the upstream branch, as well.
+-q::
+--quiet::
+ Be more quiet when creating or deleting a branch, suppressing
+ non-error messages.
+
--abbrev=<length>::
Alter the sha1's minimum display length in the output listing.
The default value is 7 and can be overridden by the `core.abbrev`
-t <file>::
--template=<file>::
- Use the contents of the given file as the initial version
- of the commit message. The editor is invoked and you can
- make subsequent changes. If a message is specified using
- the `-m` or `-F` options, this option has no effect. This
- overrides the `commit.template` configuration variable.
+ When editing the commit message, start the editor with the
+ contents in the given file. The `commit.template` configuration
+ variable is often used to give this option implicitly to the
+ command. This mechanism can be used by projects that want to
+ guide participants with some hints on what to write in the message
+ in what order. If the user exits the editor without editing the
+ message, the commit is aborted. This has no effect when a message
+ is given by other means, e.g. with the `-m` or `-F` options.

+The full syntax for a p4 view is documented in 'p4 help views'. 'Git p4'
knows only a subset of the view syntax. It understands multi-line
mappings, overlays with '+', exclusions with '-' and double-quotes

-'...', and only when it is at the end of the path. Git-p4 will complain

Bugs in the implementation of overlap mappings exist. If multiple depot
paths map through overlays to the same location in the repository,
-git-p4 can choose the wrong one. This is hard to solve without

+ 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.

+
+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
+

+NAME
+----
+git-subtree - Merge subtrees together and split repository into subtrees
+
+
+SYNOPSIS
+--------
+[verse]
+'git subtree' add -P <prefix> <commit>
+'git subtree' pull -P <prefix> <repository> <refspec...>
+'git subtree' push -P <prefix> <repository> <refspec...>
+'git subtree' merge -P <prefix> <commit>
+'git subtree' split -P <prefix> [OPTIONS] [<commit>]
+
+
+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

+ 'git subtree rejoin' option to do the same as --rejoin, eg. after a
+ rebase
+
+ --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.

+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:
