+Writing Documentation:
+
+ Every user-visible change should be reflected in the documentation.
+ The same general rule as for code applies -- imitate the existing
+ conventions.  A few commented examples follow to provide reference
+ when writing or modifying command usage strings and synopsis sections
+ in the manual pages:
+
+ Placeholders are enclosed in angle brackets:
+   <file>
+   --sort=<key>
+   --abbrev[=<n>]
+
+ Possibility of multiple occurences is indicated by three dots:
+   <file>...
+   (One or more of <file>.)
+
+ Optional parts are enclosed in square brackets:
+   [<extra>]
+   (Zero or one <extra>.)
+
+   --exec-path[=<path>]
+   (Option with an optional argument.  Note that the "=" is inside the
+   brackets.)
+
+   [<patch>...]
+   (Zero or more of <patch>.  Note that the dots are inside, not
+   outside the brackets.)
+
+ Multiple alternatives are indicated with vertical bar:
+   [-q | --quiet]
+   [--utf8 | --no-utf8]
+
+ Parentheses are used for grouping:
+   [(<rev>|<range>)...]
+   (Any number of either <rev> or <range>.  Parens are needed to make
+   it clear that "..." pertains to both <rev> and <range>.)
+
+   [(-p <parent>)...]
+   (Any number of option -p, each with one <parent> argument.)
+
+   git remote set-head <name> (-a | -d | <branch>)
+   (One and only one of "-a", "-d" or "<branch>" _must_ (no square
+   brackets) be provided.)
+
+ And a somewhat more contrived example:
+   --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]
+   Here "=" is outside the brackets, because "--diff-filter=" is a
+   valid usage.  "*" has its own pair of brackets, because it can
+   (optionally) be specified only when one or more of the letters is
+   also provided.

+Git v1.7.2.3 Release Notes
+==========================
+
+Fixes since v1.7.2.2
+--------------------
+
+ * When people try insane things such as delta-compressing 4GiB files, we
+   threw an assertion failure.
+
+ * "git archive" gave the full commit ID for "$Format:%h$".
+
+ * "git fetch --tags" did not fetch tags when remote.<nick>.tagopt was set
+   to --no-tags.  The command line option now overrides the configuration
+   setting.
+
+ * "git for-each-ref --format='%(objectname:short)'" has been completely
+   broken for a long time.
+
+ * "git gc" incorrectly pruned a rerere record that was created long
+   time ago but still is actively and repeatedly used.
+
+ * "git log --follow -M -p" was seriously broken in 1.7.2, reporting
+   assertion failure.
+
+ * Running "git log" with an incorrect option started pager nevertheless,
+   forcing the user to dismiss it.
+
+ * "git rebase" did not work well when the user has diff.renames
+   configuration variable set.
+
+ * An earlier (and rather old) fix to "git rebase" against a rebased
+   upstream broke a more normal, non rebased upstream case rather badly,
+   attempting to re-apply patches that are already accepted upstream.
+
+ * "git submodule sync" forgot to update the superproject's config file
+   when submodule URL changed.
+
+ * "git pack-refs --all --prune" did not remove a directory that has
+   become empty.

+Git v1.7.2.4 Release Notes
+==========================
+
+This is primarily to backport support for the new "add.ignoreErrors"
+name given to the existing "add.ignore-errors" configuration variable.
+
+The next version, Git 1.7.4, and future versions, will support both
+old and incorrect name and the new corrected name, but without this
+backport, users who want to use the new name "add.ignoreErrors" in
+their repositories cannot use older versions of Git.

+Git v1.7.2 Release Notes
+========================
+
+Updates since v1.7.1
+--------------------
+
+ * core.eol configuration and text/eol attributes are the new way to control
+   the end of line conventions for files in the working tree.
+
+ * core.autocrlf has been made safer - it will now only handle line
+   endings for new files and files that are LF-only in the
+   repository. To normalize content that has been checked in with
+   CRLF, use the new eol/text attributes.
+
+ * The whitespace rules used in "git apply --whitespace" and "git diff"
+   gained a new member in the family (tab-in-indent) to help projects with
+   policy to indent only with spaces.
+
+ * When working from a subdirectory, by default, git does not look for its
+   metadirectory ".git" across filesystems, primarily to help people who
+   have invocations of git in their custom PS1 prompts, as being outside
+   of a git repository would look for ".git" all the way up to the root
+   directory, and NFS mounts are often slow.  DISCOVERY_ACROSS_FILESYSTEM
+   environment variable can be used to tell git not to stop at a
+   filesystem boundary.
+
+ * Usage help messages generated by parse-options library (i.e. most
+   of the Porcelain commands) are sent to the standard output now.
+
+ * ':/<string>' notation to look for a commit now takes regular expression
+   and it is not anchored at the beginning of the commit log message
+   anymore (this is a backward incompatible change).
+
+ * "git" wrapper learned "-c name=value" option to override configuration
+   variable from the command line.
+
+ * Improved portability for various platforms including older SunOS,
+   HP-UX 10/11, AIX, Tru64, etc. and platforms with Python 2.4.
+
+ * The message from "git am -3" has been improved when conflict
+   resolution ended up making the patch a no-op.
+
+ * "git blame" applies the textconv filter to the contents it works
+   on, when available.
+
+ * "git checkout --orphan newbranch" is similar to "-b newbranch" but
+   prepares to create a root commit that is not connected to any existing
+   commit.
+
+ * "git cherry-pick" learned to pick a range of commits
+   (e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git
+   revert"; these do not support the nicer sequencing control "rebase
+   [-i]" has, though.
+
+ * "git cherry-pick" and "git revert" learned --strategy option to specify
+   the merge strategy to be used when performing three-way merges.
+
+ * "git cvsserver" can be told to use pserver; its password file can be
+   stored outside the repository.
+
+ * The output from the textconv filter used by "git diff" can be cached to
+   speed up their reuse.
+
+ * "git diff --word-diff=<mode>" extends the existing "--color-words"
+   option, making it more useful in color-challenged environments.
+
+ * The regexp to detect function headers used by "git diff" for PHP has
+   been enhanced for visibility modifiers (public, protected, etc.) to
+   better support PHP5.
+
+ * "diff.noprefix" configuration variable can be used to implicitly
+   ask for "diff --no-prefix" behaviour.
+
+ * "git for-each-ref" learned "%(objectname:short)" that gives the object
+   name abbreviated.
+
+ * "git format-patch" learned --signature option and format.signature
+   configuration variable to customize the e-mail signature used in the
+   output.
+
+ * Various options to "git grep" (e.g. --count, --name-only) work better
+   with binary files.
+
+ * "git grep" learned "-Ovi" to open the files with hits in your editor.
+
+ * "git help -w" learned "chrome" and "chromium" browsers.
+
+ * "git log --decorate" shows commit decorations in various colours.
+
+ * "git log --follow <path>" follows across copies (it used to only follow
+   renames).  This may make the processing more expensive.
+
+ * "git log --pretty=format:<template>" specifier learned "% <something>"
+   magic that inserts a space only when %<something> expands to a
+   non-empty string; this is similar to "%+<something>" magic, but is
+   useful in a context to generate a single line output.
+
+ * "git notes prune" learned "-n" (dry-run) and "-v" options, similar to
+   what "git prune" has.
+
+ * "git patch-id" can be fed a mbox without getting confused by the
+   signature line in the format-patch output.
+
+ * "git remote" learned "set-branches" subcommand.
+
+ * "git rev-list A..B" learned --ancestry-path option to further limit
+   the result to the commits that are on the ancestry chain between A and
+   B (i.e. commits that are not descendants of A are excluded).
+
+ * "git show -5" is equivalent to "git show --do-walk 5"; this is similar
+   to the update to make "git show master..next" walk the history,
+   introduced in 1.6.4.
+
+ * "git status [-s] --ignored" can be used to list ignored paths.
+
+ * "git status -s -b" shows the current branch in the output.
+
+ * "git status" learned "--ignore-submodules" option.
+
+ * Various "gitweb" enhancements and clean-ups, including syntax
+   highlighting, "plackup" support for instaweb, .fcgi suffix to run
+   it as FastCGI script, etc.
+
+ * The test harness has been updated to produce TAP-friendly output.
+
+ * Many documentation improvement patches are also included.
+
+
+Fixes since v1.7.1
+------------------
+
+All of the fixes in v1.7.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * We didn't URL decode "file:///path/to/repo" correctly when path/to/repo
+   had percent-encoded characters (638794c, 9d2e942, ce83eda, 3c73a1d).
+
+ * "git clone" did not configure remote.origin.url correctly for bare
+   clones (df61c889).
+
+ * "git diff --graph" works better with "--color-words" and other options
+   (81fa024..4297c0a).
+
+ * "git diff" could show ambiguous abbreviation of blob object names on
+   its "index" line (3e5a188).
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+   a nonstandard location is in use got confused (560fb6a1).
+
+ * "git read-tree -m A B" used to switch to branch B while retaining
+   local changes added an incorrect cache-tree information (b1f47514).

+Git v1.7.3.3 Release Notes
+==========================
+
+In addition to the usual fixes, this release also includes support for
+the new "add.ignoreErrors" name given to the existing "add.ignore-errors"
+configuration variable.
+
+The next version, Git 1.7.4, and future versions, will support both
+old and incorrect name and the new corrected name, but without this

+
+Fixes since v1.7.3.2
+--------------------
+
+ * "git apply" segfaulted when a bogus input is fed to it.
+
+ * Running "git cherry-pick --ff" on a root commit segfaulted.
+
+ * "diff", "blame" and friends incorrectly applied textconv filters to
+   symlinks.
+
+ * Highlighting of whitespace breakage in "diff" output was showing
+   incorrect amount of whitespaces when blank-at-eol is set and the line
+   consisted only of whitespaces and a TAB.
+
+ * "diff" was overly inefficient when trying to find the line to use for
+   the function header (i.e. equivalent to --show-c-function of GNU diff).
+
+ * "git imap-send" depends on libcrypto but our build rule relied on the
+   linker to implicitly link it via libssl, which was wrong.
+
+ * "git merge-file" can be called from within a subdirectory now.
+
+ * "git repack -f" expanded and recompressed non-delta objects in the
+   existing pack, which was wasteful.  Use new "-F" option if you really
+   want to (e.g. when changing the pack.compression level).
+
+ * "git rev-list --format="...%x00..." incorrectly chopped its output
+   at NUL.
+
+ * "git send-email" did not correctly remove duplicate mail addresses from
+   the Cc: header that appear on the To: header.
+
+ * The completion script (in contrib/completion) ignored lightweight tags
+   in __git_ps1().
+
+ * "git-blame" mode (in contrib/emacs) didn't say (require 'format-spec)
+   even though it depends on it; it didn't work with Emacs 22 or older
+   unless Gnus is used.
+
+ * "git-p4" (in contrib/) did not correctly handle deleted files.
+
+Other minor fixes and documentation updates are also included.

+Git v1.7.3.4 Release Notes
+==========================
+
+Fixes since v1.7.3.3
+--------------------
+
+ * Smart HTTP transport used to incorrectly retry redirected POST
+   request with GET request.
+
+ * "git apply" did not correctly handle patches that only change modes
+   if told to apply while stripping leading paths with -p option.
+
+ * "git apply" can deal with patches with timezone formatted with a
+   colon between the hours and minutes part (e.g. "-08:00" instead of
+   "-0800").
+
+ * "git checkout" removed an untracked file "foo" from the working
+   tree when switching to a branch that contains a tracked path
+   "foo/bar".  Prevent this, just like the case where the conflicting
+   path were "foo" (c752e7f..7980872d).
+
+ * "git cherry-pick" or "git revert" refused to work when a path that
+   would be modified by the operation was stat-dirty without a real
+   difference in the contents of the file.
+
+ * "git diff --check" reported an incorrect line number for added
+   blank lines at the end of file.
+
+ * "git imap-send" failed to build under NO_OPENSSL.
+
+ * Setting log.decorate configuration variable to "0" or "1" to mean
+   "false" or "true" did not work.
+
+ * "git push" over dumb HTTP protocol did not work against WebDAV
+   servers that did not terminate a collection name with a slash.
+
+ * "git tag -v" did not work with GPG signatures in rfc1991 mode.
+
+ * The post-receive-email sample hook was accidentally broken in 1.7.3.3
+   update.
+
+ * "gitweb" can sometimes be tricked into parrotting a filename argument
+   given in a request without properly quoting.
+

+Git v1.7.3 Release Notes
+========================
+
+Updates since v1.7.2
+--------------------
+
+ * git-gui, now at version 0.13.0, got various updates and a new
+   maintainer, Pat Thoyts.
+
+ * Gitweb allows its configuration to change per each request; it used to
+   read the configuration once upon startup.
+
+ * When git finds a corrupt object, it now reports the file that contains
+   it.
+
+ * "git checkout -B <it>" is a shorter way to say "git branch -f <it>"
+   followed by "git checkout <it>".
+
+ * When "git checkout" or "git merge" refuse to proceed in order to
+   protect local modification to your working tree, they used to stop
+   after showing just one path that might be lost.  They now show all,
+   in a format that is easier to read.
+
+ * "git clean" learned "-e" ("--exclude") option.
+
+ * Hunk headers produced for C# files by "git diff" and friends show more
+   relevant context than before.
+
+ * diff.ignoresubmodules configuration variable can be used to squelch the
+   differences in submodules reported when running commands (e.g. "diff",
+   "status", etc.) at the superproject level.
+
+ * http.useragent configuration can be used to lie who you are to your
+   restrictive firewall.
+
+ * "git rebase --strategy <s>" learned "-X" option to pass extra options
+   that are understood by the chosen merge strategy.
+
+ * "git rebase -i" learned "exec" that you can insert into the insn sheet
+   to run a command between its steps.
+
+ * "git rebase" between branches that have many binary changes that do
+   not conflict should be faster.
+
+ * "git rebase -i" peeks into rebase.autosquash configuration and acts as
+   if you gave --autosquash from the command line.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.2
+------------------
+
+All of the fixes in v1.7.2.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git merge -s recursive" (which is the default) did not handle cases
+   where a directory becomes a file (or vice versa) very well.
+
+ * "git fetch" and friends were accidentally broken for url with "+" in
+   its path, e.g. "git://git.gnome.org/gtk+".
+
+ * "git fetch $url" (i.e. without refspecs) was broken for quite some
+   time, if the current branch happen to be tracking some remote.
+
+ * "git ls-tree dir dirgarbage", when "dir" was a directory,
+   incorrectly recursed into "dir".
+
+ * "git note remove" created unnecessary extra commit when named object
+   did not have any note to begin with.
+
+ * "git rebase" did not work well if you had diff.noprefix configured.
+
+ * "git -c foo=bar subcmd" did not work well for subcmd that is not
+   implemented as a built-in command.

+Git v1.7.4 Release Notes (draft)
+================================
+
+Updates since v1.7.3
+--------------------
+
+ * The documentation Makefile now assumes by default asciidoc 8 and
+   docbook-xsl >= 1.73. If you have older versions, you can set
+   ASCIIDOC7 and ASCIIDOC_ROFF, respectively.
+
+ * The option parsers of various commands that create new branch (or
+   rename existing ones to a new name) were too loose and users were
+   allowed to call a branch with a name that begins with a dash by
+   creative abuse of their command line options, which only lead to
+   burn themselves.  The name of a branch cannot begin with a dash
+   now.
+
+ * System-wide fallback default attributes can be stored in
+   /etc/gitattributes; core.attributesfile configuration variable can
+   be used to customize the path to this file.
+
+ * The thread structure generated by "git send-email" has changed
+   slightly.  Setting the cover letter of the latest series as a reply
+   to the cover letter of the previous series with --in-reply-to used
+   to make the new cover letter and all the patches replies to the
+   cover letter of the previous series; this has been changed to make
+   the patches in the new series replies to the new cover letter.
+
+ * Bash completion script in contrib/ has been adjusted to be also
+   usable by zsh.
+
+ * "git blame" learned --show-email option to display the e-mail
+   addresses instead of the names of authors.
+
+ * "git daemon" can be built in MinGW environment.
+
+ * "git daemon" can take more than one --listen option to listen to
+   multiple addresses.
+
+ * "git diff" and "git grep" learned how functions and subroutines
+   in Fortran look like.
+
+ * "git mergetool" tells vim/gvim to show three-way diff by default
+   (use vimdiff2/gvimdiff2 as the tool name for old behaviour).
+
+ * "git log -G<pattern>" limits the output to commits whose change has
+   added or deleted lines that match the given pattern.
+
+ * "git read-tree" with no argument as a way to empty the index is
+   deprecated; we might want to remove it in the future.  Users can
+   use the new --empty option to be more explicit instead.
+
+ * "git repack -f" does not spend cycles to recompress objects in the
+   non-delta representation anymore (use -F if you really mean it when
+   e.g. you changed the compression level).
+
+ * "git merge --log" used to limit the resulting merge log to 20
+   entries; this is now customizable by giving e.g. "--log=47".
+
+ * "git merge" may work better when all files were moved out of a
+   directory in one branch while a new file is created in place of that
+   directory in the other branch.
+
+ * "git rebase --autosquash" can use SHA-1 object names to name which
+   commit to fix up (e.g. "fixup! e83c5163").
+
+ * The default "recursive" merge strategy learned --rename-threshold
+   option to influence the rename detection, similar to the -M option
+   of "git diff".  E.g. "git merge -Xrename-threshold=50% ..." to use
+   this.
+
+ * The "recursive" strategy also learned to ignore various whitespace
+   changes; the most notable is -Xignore-space-at-eol.
+
+ * "git send-email" learned "--to-cmd", similar to "--cc-cmd", to read
+   recipient list from a command output.
+
+ * "git send-email" learned to read and use "To:" from its input files.
+
+ * you can extend "git shell", which is often used on boxes that allow
+   git-only login over ssh as login shell, with custom set of
+   commands.
+
+ * "git submodule sync" updates metainformation for all submodules,
+   not just the ones that have been checked out.
+
+ * gitweb can use custom 'highlight' command with its configuration file.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.3
+------------------
+
+All of the fixes in v1.7.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git log --author=me --author=her" did not find commits written by
+   me or by her; instead it looked for commits written by me and by
+   her, which is impossible.
+
+ * "git merge" into an unborn branch removed an untracked file "foo"
+   from the working tree when merged branch had "foo" (2caf20c..172b642).
+
+ * "git push --progress" shows progress indicators now.
+
+ * "git repack" places its temporary packs under $GIT_OBJECT_DIRECTORY/pack
+   instead of $GIT_OBJECT_DIRECTORY/ to avoid cross directory renames.
+
+ * "git submodule update --recursive --other-flags" passes flags down
+   to its subinvocations.

+selector will open a patch in your editor; after the editor exits, the
+result is applied to the index. You are free to make arbitrary changes
+to the patch, but note that some changes may have confusing results, or
+even result in a patch that cannot be applied.  If you want to abort the
+operation entirely (i.e., stage nothing new in the index), simply delete
+all lines of the patch. The list below describes some common things you
+may see in a patch, and which editing operations make sense on them.
+
+--
+added content::
+
+Added content is represented by lines beginning with "{plus}". You can
+prevent staging any addition lines by deleting them.
+
+removed content::
+
+Removed content is represented by lines beginning with "-". You can
+prevent staging their removal by converting the "-" to a " " (space).
+
+modified content::
+
+Modified content is represented by "-" lines (removing the old content)
+followed by "{plus}" lines (adding the replacement content). You can
+prevent staging the modification by converting "-" lines to " ", and
+removing "{plus}" lines. Beware that modifying only half of the pair is
+likely to introduce confusing changes to the index.
+--
+
+There are also more complex operations that can be performed. But beware
+that because the patch is applied only to the index and not the working
+tree, the working tree will appear to "undo" the change in the index.
+For example, introducing a a new line into the index that is in neither
+the HEAD nor the working tree will stage the new line for commit, but
+the line will appear to be reverted in the working tree.
+
+Avoid using these constructs, or do so with extreme caution.
+
+--
+removing untouched content::
+
+Content which does not differ between the index and working tree may be
+shown on context lines, beginning with a " " (space).  You can stage
+context lines for removal by converting the space to a "-". The
+resulting working tree file will appear to re-add the content.
+
+modifying existing content::
+
+One can also modify context lines by staging them for removal (by
+converting " " to "-") and adding a "{plus}" line with the new content.
+Similarly, one can modify "{plus}" lines for existing additions or
+modifications. In all cases, the new modification will appear reverted
+in the working tree.
+
+new content::
+
+You may also add new content that does not exist in the patch; simply
+add new lines, each starting with "{plus}". The addition will appear
+reverted in the working tree.
+--
+
+There are also several operations which should be avoided entirely, as
+they will make the patch impossible to apply:
+
+* adding context (" ") or removal ("-") lines
+* deleting context or removal lines
+* modifying the contents of context or removal lines

+NOTES MERGE STRATEGIES
+----------------------
+
+The default notes merge strategy is "manual", which checks out
+conflicting notes in a special work tree for resolving notes conflicts
+(`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the
+conflicts in that work tree.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+"ours" automatically resolves conflicting notes in favor of the local
+version (i.e. the current notes ref).
+
+"theirs" automatically resolves notes conflicts in favor of the remote
+version (i.e. the given notes ref being merged into the current notes
+ref).
+
+"union" automatically resolves notes conflicts by concatenating the
+local and remote versions.
+
+"cat_sort_uniq" is similar to "union", but in addition to concatenating
+the local and remote versions, this strategy also sorts the resulting
+lines, and removes duplicate lines from the result. This is equivalent
+to applying the "cat | sort | uniq" shell pipeline to the local and
+remote versions. This strategy is useful if the notes follow a line-based
+format where one wants to avoid duplicated lines in the merge result.
+Note that if either the local or remote version contain duplicate lines
+prior to the merge, these will also be removed by this notes merge
+strategy.

+=================
+
+NAME
+----
+git-remote-ext - Bridge smart transport to external command.
+
+SYNOPSIS
+--------
+git remote add nick "ext::<command>[ <arguments>...]"
+
+DESCRIPTION
+-----------
+This remote helper uses the specified 'program' to connect
+to a remote git server.
+
+Data written to stdin of this specified 'program' is assumed
+to be sent to git:// server, git-upload-pack, git-receive-pack
+or git-upload-archive (depending on situation), and data read
+from stdout of this program is assumed to be received from
+the same service.
+
+Command and arguments are separated by unescaped space.
+
+The following sequences have a special meaning:
+
+'% '::
+       Literal space in command or argument.
+
+'%%'::
+       Literal percent sign.
+
+'%s'::
+       Replaced with name (receive-pack, upload-pack, or
+       upload-archive) of the service git wants to invoke.
+
+'%S'::
+       Replaced with long name (git-receive-pack,
+       git-upload-pack, or git-upload-archive) of the service
+       git wants to invoke.
+
+'%G' (must be first characters in argument)::
+       This argument will not be passed to 'program'. Instead, it
+       will cause helper to start by sending git:// service request to
+       remote side with service field set to approiate value and
+       repository field set to rest of the argument. Default is not to send
+       such request.
++
+This is useful if remote side is git:// server accessed over
+some tunnel.
+
+'%V' (must be first characters in argument)::
+       This argument will not be passed to 'program'. Instead it sets
+       the vhost field in git:// service request (to rest of the argument).
+       Default is not to send vhost in such request (if sent).
+
+ENVIRONMENT VARIABLES:
+----------------------
+
+GIT_TRANSLOOP_DEBUG::
+       If set, prints debugging information about various reads/writes.
+
+ENVIRONMENT VARIABLES PASSED TO COMMAND:
+----------------------------------------
+
+GIT_EXT_SERVICE::
+       Set to long name (git-upload-pack, etc...) of service helper needs
+       to invoke.
+
+GIT_EXT_SERVICE_NOPREFIX::
+       Set to long name (upload-pack, etc...) of service helper needs
+       to invoke.
+
+
+EXAMPLES:
+---------
+This remote helper is transparently used by git when
+you use commands such as "git fetch <URL>", "git clone <URL>",
+, "git push <URL>" or "git remote add nick <URL>", where <URL>
+begins with `ext::`.  Examples:
+
+"ext::ssh -i /home/foo/.ssh/somekey user&#64;host.example %S 'foo/repo'"::
+       Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
+       keypair and user as user on remote side. This avoids needing to
+       edit .ssh/config.
+
+"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
+       Represents repository with path /somerepo accessable over
+       git protocol at abstract namespace address /git-server.
+
+"ext::git-server-alias foo %G/repo"::
+       Represents a repository with path /repo accessed using the
+       helper program "git-server-alias foo".  The path to the
+       repository and type of request are not passed on the command
+       line but as part of the protocol stream, as usual with git://
+       protocol.
+
+"ext::git-server-alias foo %G/repo %Vfoo"::
+       Represents a repository with path /repo accessed using the
+       helper program "git-server-alias foo".  The hostname for the
+       remote server passed in the protocol stream will be "foo"
+       (this allows multiple virtual git servers to share a
+       link-level address).
+
+"ext::git-server-alias foo %G/repo% with% spaces %Vfoo"::
+       Represents a repository with path '/repo with spaces' accessed
+       using the helper program "git-server-alias foo".  The hostname for
+       the remote server passed in the protocol stream will be "foo"
+       (this allows multiple virtual git servers to share a
+       link-level address).
+
+"ext::git-ssl foo.example /bar"::
+       Represents a repository accessed using the helper program
+       "git-ssl foo.example /bar".  The type of request can be
+       determined by the helper using environment variables (see
+       above).

+NAME
+----
+git-remote-fd - Reflect smart transport stream back to caller
+
+SYNOPSIS
+--------
+"fd::<infd>[,<outfd>][/<anything>]" (as URL)
+
+DESCRIPTION
+-----------
+This helper uses specified file descriptors to connect to remote git server.
+This is not meant for end users but for programs and scripts calling git
+fetch, push or archive.
+
+If only <infd> is given, it is assumed to be bidirectional socket connected
+to remote git server (git-upload-pack, git-receive-pack or
+git-upload-achive). If both <infd> and <outfd> are given, they are assumed
+to be pipes connected to remote git server (<infd> being the inbound pipe
+and <outfd> being the outbound pipe.
+
+It is assumed that any handshaking procedures have already been completed
+(such as sending service request for git://) before this helper is started.
+
+<anything> can be any string. It is ignored. It is meant for provoding
+information to user in the URL in case that URL is displayed in some
+context.
+
+ENVIRONMENT VARIABLES

+       git-upload-pack.
+
+git fetch fd::17/foo master::

+
+git push fd::7,8 master (as URL)::
+       Push master, using file descriptor #7 to read data from

 DESCRIPTION
 -----------
-Sets the current head to the specified commit and optionally resets the
-index and working tree to match.
-
-This command is useful if you notice some small error in a recent
-commit (or set of commits) and want to redo that part without showing
-the undo in the history.
-
-If you want to undo a commit other than the latest on a branch,
-linkgit:git-revert[1] is your friend.
-
-The second and third forms with 'paths' and/or --patch are used to
-revert selected paths in the index from a given commit, without moving
-HEAD.
+In the first and second form, copy entries from <commit> to the index.
+In the third form, set the current branch head (HEAD) to <commit>, optionally
+modifying index and working tree to match.  The <commit> defaults to HEAD
+in all forms.
+
+'git reset' [-q] [<commit>] [--] <paths>...::
+       This form resets the index entries for all <paths> to their
+       state at <commit>.  (It does not affect the working tree, nor
+       the current branch.)
++
+This means that `git reset <paths>` is the opposite of `git add
+<paths>`.
++
+After running `git reset <paths>` to update the index entry, you can
+use linkgit:git-checkout[1] to check the contents out of the index to
+the working tree.
+Alternatively, using linkgit:git-checkout[1] and specifying a commit, you
+can copy the contents of a path out of a commit to the index and to the
+working tree in one go.
+
+'git reset' --patch|-p [<commit>] [--] [<paths>...]::
+       Interactively select hunks in the difference between the index
+       and <commit> (defaults to HEAD).  The chosen hunks are applied
+       in reverse to the index.
++
+This means that `git reset -p` is the opposite of `git add -p` (see
+linkgit:git-add[1]).
 
+'git reset' [--<mode>] [<commit>]::
+       This form resets the current branch head to <commit> and
+       possibly updates the index (resetting it to the tree of <commit>) and
+       the working tree depending on <mode>, which
+       must be one of the following:
++
+--
+--soft::
+       Does not touch the index file nor the working tree at all (but
+       resets the head to <commit>, just like all modes do). This leaves
+       all your changed files "Changes to be committed", as 'git status'
+       would put it.
 
-OPTIONS
--------
 --mixed::
        Resets the index but not the working tree (i.e., the changed files
        are preserved but not marked for commit) and reports what has not
        been updated. This is the default action.
 
---soft::
-       Does not touch the index file nor the working tree at all, but
-       requires them to be in a good order. This leaves all your changed
-       files "Changes to be committed", as 'git status' would
-       put it.
-
 --hard::
-       Matches the working tree and index to that of the tree being
-       switched to. Any changes to tracked files in the working tree
-       since <commit> are lost.
+       Resets the index and working tree. Any changes to tracked files in the
+       working tree since <commit> are discarded.
 
 --merge::
-       Resets the index to match the tree recorded by the named commit,
-       and updates the files that are different between the named commit
-       and the current commit in the working tree.
+       Resets the index and updates the files in the working tree that are
+       different between <commit> and HEAD, but keeps those which are
+       different between the index and working tree (i.e. which have changes
+       which have not been added).
+       If a file that is different between <commit> and the index has unstaged
+       changes, reset is aborted.
++
+In other words, --merge does something like a 'git read-tree -u -m <commit>',
+but carries forward unmerged index entries.
 
 --keep::

-"reset --merge" is meant to be used when resetting out of a conflicted
-merge. Any mergy operation guarantees that the work tree file that is
-involved in the merge does not have local change wrt the index before
-it starts, and that it writes the result out to the work tree. So if
-we see some difference between the index and the target and also
-between the index and the work tree, then it means that we are not
-resetting out from a state that a mergy operation left after failing
-with a conflict. That is why we disallow --merge option in this case.
-
-"reset --keep" is meant to be used when removing some of the last
-commits in the current branch while keeping changes in the working
-tree. If there could be conflicts between the changes in the commit we
-want to remove and the changes in the working tree we want to keep,
-the reset is disallowed. That's why it is disallowed if there are both
-changes between the working tree and HEAD, and between HEAD and the
-target. To be safe, it is also disallowed when there are unmerged
-entries.

-SPECIFYING REVISIONS
---------------------
-
-A revision parameter typically, but not necessarily, names a
-commit object.  They use what is called an 'extended SHA1'
-syntax.  Here are various ways to spell object names.  The
-ones listed near the end of this list are to name trees and
-blobs contained in a commit.
-
-* The full SHA1 object name (40-byte hexadecimal string), or
-  a substring of such that is unique within the repository.
-  E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
-  name the same commit object if there are no other object in
-  your repository whose object name starts with dae86e.
-
-* An output from 'git describe'; i.e. a closest tag, optionally
-  followed by a dash and a number of commits, followed by a dash, a
-  `g`, and an abbreviated object name.
-
-* A symbolic ref name.  E.g. 'master' typically means the commit
-  object referenced by refs/heads/master.  If you
-  happen to have both heads/master and tags/master, you can
-  explicitly say 'heads/master' to tell git which one you mean.
-  When ambiguous, a `<name>` is disambiguated by taking the
-  first match in the following rules:
-
-  . if `$GIT_DIR/<name>` exists, that is what you mean (this is usually
-    useful only for `HEAD`, `FETCH_HEAD`, `ORIG_HEAD` and `MERGE_HEAD`);
-
-  . otherwise, `refs/<name>` if exists;
-
-  . otherwise, `refs/tags/<name>` if exists;
-
-  . otherwise, `refs/heads/<name>` if exists;
-
-  . otherwise, `refs/remotes/<name>` if exists;
-
-  . otherwise, `refs/remotes/<name>/HEAD` if exists.
-+
-HEAD names the commit your changes in the working tree is based on.
-FETCH_HEAD records the branch you fetched from a remote repository
-with your last 'git fetch' invocation.
-ORIG_HEAD is created by commands that moves your HEAD in a drastic
-way, to record the position of the HEAD before their operation, so that
-you can change the tip of the branch back to the state before you ran
-them easily.
-MERGE_HEAD records the commit(s) you are merging into your branch
-when you run 'git merge'.
-+
-Note that any of the `refs/*` cases above may come either from
-the `$GIT_DIR/refs` directory or from the `$GIT_DIR/packed-refs` file.
-
-* A ref followed by the suffix '@' with a date specification
-  enclosed in a brace
-  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
-  second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
-  of the ref at a prior point in time.  This suffix may only be
-  used immediately following a ref name and the ref must have an
-  existing log ($GIT_DIR/logs/<ref>). Note that this looks up the state
-  of your *local* ref at a given time; e.g., what was in your local
-  `master` branch last week. If you want to look at commits made during
-  certain times, see `--since` and `--until`.
-
-* A ref followed by the suffix '@' with an ordinal specification
-  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
-  the n-th prior value of that ref.  For example 'master@\{1\}'
-  is the immediate prior value of 'master' while 'master@\{5\}'
-  is the 5th prior value of 'master'. This suffix may only be used
-  immediately following a ref name and the ref must have an existing
-  log ($GIT_DIR/logs/<ref>).
-
-* You can use the '@' construct with an empty ref part to get at a
-  reflog of the current branch. For example, if you are on the
-  branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
-
-* The special construct '@\{-<n>\}' means the <n>th branch checked out
-  before the current one.
-
-* The suffix '@\{upstream\}' to a ref (short form 'ref@\{u\}') refers to
-  the branch the ref is set to build on top of.  Missing ref defaults
-  to the current branch.
-
-* A suffix '{caret}' to a revision parameter (e.g. 'HEAD{caret}') means the first parent of
-  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
-  'rev{caret}'
-  is equivalent to 'rev{caret}1').  As a special rule,
-  'rev{caret}0' means the commit itself and is used when 'rev' is the
-  object name of a tag object that refers to a commit object.
-
-* A suffix '{tilde}<n>' to a revision parameter means the commit
-  object that is the <n>th generation grand-parent of the named
-  commit object, following only the first parent.  I.e. rev~3 is
-  equivalent to rev{caret}{caret}{caret} which is equivalent to
-  rev{caret}1{caret}1{caret}1.  See below for a illustration of
-  the usage of this form.
-
-* A suffix '{caret}' followed by an object type name enclosed in
-  brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
-  could be a tag, and dereference the tag recursively until an
-  object of that type is found or the object cannot be
-  dereferenced anymore (in which case, barf).  `rev{caret}0`
-  introduced earlier is a short-hand for `rev{caret}\{commit\}`.
-
-* A suffix '{caret}' followed by an empty brace pair
-  (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
-  and dereference the tag recursively until a non-tag object is
-  found.
-
-* A colon, followed by a slash, followed by a text (e.g. `:/fix nasty bug`): this names
-  a commit whose commit message starts with the specified text.
-  This name returns the youngest matching commit which is
-  reachable from any ref.  If the commit message starts with a
-  '!', you have to repeat that;  the special sequence ':/!',
-  followed by something else than '!' is reserved for now.
-
-* A suffix ':' followed by a path (e.g. `HEAD:README`); this names the blob or tree
-  at the given path in the tree-ish object named by the part
-  before the colon.
-  ':path' (with an empty part before the colon, e.g. `:README`)
-  is a special case of the syntax described next: content
-  recorded in the index at the given path.
-
-* A colon, optionally followed by a stage number (0 to 3) and a
-  colon, followed by a path (e.g. `:0:README`); this names a blob object in the
-  index at the given path. Missing stage number (and the colon
-  that follows it, e.g. `:README`) names a stage 0 entry. During a merge, stage
-  1 is the common ancestor, stage 2 is the target branch's version
-  (typically the current branch), and stage 3 is the version from
-  the branch being merged.
-
-Here is an illustration, by Jon Loeliger.  Both commit nodes B
-and C are parents of commit node A.  Parent commits are ordered
-left-to-right.

-SPECIFYING RANGES
------------------
-
-History traversing commands such as 'git log' operate on a set
-of commits, not just a single commit.  To these commands,
-specifying a single revision with the notation described in the
-previous section means the set of commits reachable from that
-commit, following the commit ancestry chain.
-
-To exclude commits reachable from a commit, a prefix `{caret}`
-notation is used.  E.g. `{caret}r1 r2` means commits reachable
-from `r2` but exclude the ones reachable from `r1`.
-
-This set operation appears so often that there is a shorthand
-for it.  When you have two commits `r1` and `r2` (named according
-to the syntax explained in SPECIFYING REVISIONS above), you can ask
-for commits that are reachable from r2 excluding those that are reachable
-from r1 by `{caret}r1 r2` and it can be written as `r1..r2`.
-
-A similar notation `r1\...r2` is called symmetric difference
-of `r1` and `r2` and is defined as
-`r1 r2 --not $(git merge-base --all r1 r2)`.
-It is the set of commits that are reachable from either one of
-`r1` or `r2` but not from both.
-
-Two other shorthands for naming a set that is formed by a commit
-and its parent commits exist.  The `r1{caret}@` notation means all
-parents of `r1`.  `r1{caret}!` includes commit `r1` but excludes
-all of its parents.
-
-Here are a handful of examples:
-
-   D                G H D
-   D F              G H I J D F
-   ^G D             H D
-   ^D B             E I J F B
-   B...C            G H D E B C
-   ^D B C           E I J F B C
-   C^@              I J F

 NAME

-git-shell - Restricted login shell for GIT-only SSH access
+git-shell - Restricted login shell for Git-only SSH access
 
 
 SYNOPSIS
 --------
-'$(git --exec-path)/git-shell' -c <command> <argument>
+'git shell' [-c <command> <argument>]
 
 DESCRIPTION
 -----------
-This is meant to be used as a login shell for SSH accounts you want
-to restrict to GIT pull/push access only. It permits execution only
-of server-side GIT commands implementing the pull/push functionality.
-The commands can be executed only by the '-c' option; the shell is not
-interactive.
-
-Currently, only four commands are permitted to be called, 'git-receive-pack'
-'git-upload-pack' and 'git-upload-archive' with a single required argument, or
-'cvs server' (to invoke 'git-cvsserver').
+
+A login shell for SSH accounts to provide restricted Git access. When
+'-c' is given, the program executes <command> non-interactively;
+<command> can be one of 'git receive-pack', 'git upload-pack', 'git
+upload-archive', 'cvs server', or a command in COMMAND_DIR. The shell
+is started in interactive mode when no arguments are given; in this
+case, COMMAND_DIR must exist, and any of the executables in it can be
+invoked.
+
+'cvs server' is a special command which executes git-cvsserver.
+
+COMMAND_DIR is the path "$HOME/git-shell-commands". The user must have
+read and execute permissions to the directory in order to execute the
+programs in it. The programs are executed with a cwd of $HOME, and
+<argument> is parsed as a command-line string.

+       This setting forces git to normalize line endings for this
+       file on checkin and convert them to CRLF when the file is

+

+
+       This setting forces git to normalize line endings to LF on

+
+Backwards compatibility with `crlf` attribute
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For backwards compatibility, the `crlf` attribute is interpreted as
+follows:
+
+------------------------
+crlf           text
+-crlf          -text
+crlf=input     eol=lf
+------------------------
+
+End-of-line conversion
+^^^^^^^^^^^^^^^^^^^^^^
 
-If the configuration variable `core.autocrlf` is false, no
-conversion is done.
+While git normally leaves file contents alone, it can be configured to
+normalize line endings to LF in the repository and, optionally, to
+convert them to CRLF when files are checked out.
 
-When `core.autocrlf` is true, it means that the platform wants
-CRLF line endings for files in the working tree, and you want to
-convert them back to the normal LF line endings when checking
-in to the repository.
+Here is an example that will make git normalize .txt, .vcproj and .sh
+files, ensure that .vcproj files have CRLF and .sh files have LF in
+the working directory, and prevent .jpg files from being normalized
+regardless of their content.
 
-When `core.autocrlf` is set to "input", line endings are
-converted to LF upon checkin, but there is no conversion done
-upon checkout.
+------------------------
+*.txt          text
+*.vcproj       eol=crlf
+*.sh           eol=lf
+*.jpg          -text
+------------------------
+
+Other source code management systems normalize all text files in their
+repositories, and there are two ways to enable similar automatic
+normalization in git.
+
+If you simply want to have CRLF line endings in your working directory
+regardless of the repository you are working with, you can set the
+config variable "core.autocrlf" without changing any attributes.
+
+------------------------
+[core]
+       autocrlf = true
+------------------------
+
+This does not force normalization of all text files, but does ensure
+that text files that you introduce to the repository have their line
+endings normalized to LF when they are added, and that files that are
+already normalized in the repository stay normalized.
+
+If you want to interoperate with a source code management system that
+enforces end-of-line normalization, or you simply want all text files
+in your repository to be normalized, you should instead set the `text`
+attribute to "auto" for _all_ files.
+
+------------------------
+*      text=auto
+------------------------
+
+This ensures that all files that git considers to be text will have
+normalized (LF) line endings in the repository.  The `core.eol`
+configuration variable controls which line endings git will use for
+normalized files in your working directory; the default is to use the
+native line ending for your platform, or CRLF if `core.autocrlf` is
+set.
+
+NOTE: When `text=auto` normalization is enabled in an existing
+repository, any text files containing CRLFs should be normalized.  If
+they are not they will be normalized the next time someone tries to
+change them, causing unfortunate misattribution.  From a clean working
+directory:
+
+-------------------------------------------------
+$ echo "* text=auto" >>.gitattributes
+$ rm .git/index     # Remove the index to force git to

+$ git status        # Show files that will be normalized
+$ git add -u
+$ git add .gitattributes
+$ git commit -m "Introduce end-of-line normalization"

+If any files that should not be normalized show up in 'git status',
+unset their `text` attribute before running 'git add -u'.

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you have added attributes to a file that cause the canonical
+repository format for that file to change, such as adding a
+clean/smudge filter or text/eol/ident attributes, merging anything
+where the attribute is not in place would normally cause merge
+conflicts.
+
+To prevent these unnecessary merge conflicts, git can be told to run a
+virtual check-out and check-in of all three stages of a file when
+resolving a three-way merge by setting the `merge.renormalize`
+configuration variable.  This prevents changes caused by check-in
+conversion from causing spurious merge conflicts when a converted file
+is merged with an unconverted file.
+
+As long as a "smudge->clean" results in the same output as a "clean"
+even on files that are already smudged, this strategy will
+automatically resolve all filter-related conflicts.  Filters that do
+not act in this way may cause additional merge conflicts that must be

+NAME
+----
+gitrevisions - specifying revisions and ranges for git
+
+SYNOPSIS
+--------
+gitrevisions
+
+
+DESCRIPTION
+-----------
+
+Many Git commands take revision parameters as arguments. Depending on
+the command, they denote a specific commit or, for commands which
+walk the revision graph (such as linkgit:git-log[1]), all commits which can
+be reached from that commit. In the latter case one can also specify a
+range of revisions explicitly.
+
+In addition, some Git commands (such as linkgit:git-show[1]) also take
+revision parameters which denote other objects than commits, e.g. blobs
+("files") or trees ("directories of files").

+       Limit the displayed commits to those directly on the ancestry
+       chain between the "from" and "to" commits in the given commit
+       range. I.e. only display commits that are ancestor of the "to"
+       commit, and descendants of the "from" commit.
++
+As an example use case, consider the following commit history:
++
+-----------------------------------------------------------------------
+           D---E-------F
+          /     \       \
+         B---C---G---H---I---J
+        /                     \
+       A-------K---------------L--M
+-----------------------------------------------------------------------
++
+A regular 'D..M' computes the set of commits that are ancestors of `M`,
+but excludes the ones that are ancestors of `D`. This is useful to see
+what happened to the history leading to `M` since `D`, in the sense
+that "what does `M` have that did not exist in `D`". The result in this
+example would be all the commits, except `A` and `B` (and `D` itself,
+of course).
++
+When we want to find out what commits in `M` are contaminated with the
+bug introduced by `D` and need fixing, however, we might want to view
+only the subset of 'D..M' that are actually descendants of `D`, i.e.
+excluding `C` and `K`. This is exactly what the '\--ancestry-path'
+option does. Applied to the 'D..M' range, it results in:
++
+-----------------------------------------------------------------------
+               E-------F
+                \       \
+                 G---H---I---J
+                              \
+                               L--M
+-----------------------------------------------------------------------
+
 The '\--simplify-by-decoration' option allows you to view only the
 big picture of the topology of the history, by omitting commits
 that are not referenced by tags.  Commits are marked as !TREESAME

+SPECIFYING REVISIONS
+--------------------
+
+A revision parameter typically, but not necessarily, names a
+commit object.  They use what is called an 'extended SHA1'
+syntax.  Here are various ways to spell object names.  The
+ones listed near the end of this list are to name trees and
+blobs contained in a commit.
+
+* The full SHA1 object name (40-byte hexadecimal string), or
+  a substring of such that is unique within the repository.
+  E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
+  name the same commit object if there are no other object in
+  your repository whose object name starts with dae86e.
+
+* An output from 'git describe'; i.e. a closest tag, optionally
+  followed by a dash and a number of commits, followed by a dash, a
+  `g`, and an abbreviated object name.
+
+* A symbolic ref name.  E.g. 'master' typically means the commit
+  object referenced by refs/heads/master.  If you
+  happen to have both heads/master and tags/master, you can
+  explicitly say 'heads/master' to tell git which one you mean.
+  When ambiguous, a `<name>` is disambiguated by taking the
+  first match in the following rules:
+
+  . if `$GIT_DIR/<name>` exists, that is what you mean (this is usually
+    useful only for `HEAD`, `FETCH_HEAD`, `ORIG_HEAD` and `MERGE_HEAD`);
+
+  . otherwise, `refs/<name>` if exists;
+
+  . otherwise, `refs/tags/<name>` if exists;
+
+  . otherwise, `refs/heads/<name>` if exists;
+
+  . otherwise, `refs/remotes/<name>` if exists;
+
+  . otherwise, `refs/remotes/<name>/HEAD` if exists.
++
+HEAD names the commit your changes in the working tree is based on.
+FETCH_HEAD records the branch you fetched from a remote repository
+with your last 'git fetch' invocation.
+ORIG_HEAD is created by commands that moves your HEAD in a drastic
+way, to record the position of the HEAD before their operation, so that
+you can change the tip of the branch back to the state before you ran
+them easily.
+MERGE_HEAD records the commit(s) you are merging into your branch
+when you run 'git merge'.
++
+Note that any of the `refs/*` cases above may come either from
+the `$GIT_DIR/refs` directory or from the `$GIT_DIR/packed-refs` file.
+
+* A ref followed by the suffix '@' with a date specification
+  enclosed in a brace
+  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
+  second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
+  of the ref at a prior point in time.  This suffix may only be
+  used immediately following a ref name and the ref must have an
+  existing log ($GIT_DIR/logs/<ref>). Note that this looks up the state
+  of your *local* ref at a given time; e.g., what was in your local
+  `master` branch last week. If you want to look at commits made during
+  certain times, see `--since` and `--until`.
+
+* A ref followed by the suffix '@' with an ordinal specification
+  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
+  the n-th prior value of that ref.  For example 'master@\{1\}'
+  is the immediate prior value of 'master' while 'master@\{5\}'
+  is the 5th prior value of 'master'. This suffix may only be used
+  immediately following a ref name and the ref must have an existing
+  log ($GIT_DIR/logs/<ref>).
+
+* You can use the '@' construct with an empty ref part to get at a
+  reflog of the current branch. For example, if you are on the
+  branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
+
+* The special construct '@\{-<n>\}' means the <n>th branch checked out
+  before the current one.
+
+* The suffix '@\{upstream\}' to a ref (short form 'ref@\{u\}') refers to
+  the branch the ref is set to build on top of.  Missing ref defaults
+  to the current branch.
+
+* A suffix '{caret}' to a revision parameter (e.g. 'HEAD{caret}') means the first parent of
+  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
+  'rev{caret}'
+  is equivalent to 'rev{caret}1').  As a special rule,
+  'rev{caret}0' means the commit itself and is used when 'rev' is the
+  object name of a tag object that refers to a commit object.
+
+* A suffix '{tilde}<n>' to a revision parameter means the commit
+  object that is the <n>th generation grand-parent of the named
+  commit object, following only the first parent.  I.e. rev~3 is
+  equivalent to rev{caret}{caret}{caret} which is equivalent to
+  rev{caret}1{caret}1{caret}1.  See below for a illustration of
+  the usage of this form.
+
+* A suffix '{caret}' followed by an object type name enclosed in
+  brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
+  could be a tag, and dereference the tag recursively until an
+  object of that type is found or the object cannot be
+  dereferenced anymore (in which case, barf).  `rev{caret}0`
+  introduced earlier is a short-hand for `rev{caret}\{commit\}`.
+
+* A suffix '{caret}' followed by an empty brace pair
+  (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
+  and dereference the tag recursively until a non-tag object is
+  found.
+
+* A colon, followed by a slash, followed by a text (e.g. `:/fix nasty bug`): this names
+  a commit whose commit message matches the specified regular expression.
+  This name returns the youngest matching commit which is
+  reachable from any ref.  If the commit message starts with a
+  '!', you have to repeat that;  the special sequence ':/!',
+  followed by something else than '!' is reserved for now.
+  The regular expression can match any part of the commit message. To
+  match messages starting with a string, one can use e.g. `:/^foo`.
+
+* A suffix ':' followed by a path (e.g. `HEAD:README`); this names the blob or tree
+  at the given path in the tree-ish object named by the part
+  before the colon.
+  ':path' (with an empty part before the colon, e.g. `:README`)
+  is a special case of the syntax described next: content
+  recorded in the index at the given path.
+
+* A colon, optionally followed by a stage number (0 to 3) and a
+  colon, followed by a path (e.g. `:0:README`); this names a blob object in the
+  index at the given path. Missing stage number (and the colon
+  that follows it, e.g. `:README`) names a stage 0 entry. During a merge, stage
+  1 is the common ancestor, stage 2 is the target branch's version
+  (typically the current branch), and stage 3 is the version from
+  the branch being merged.
+
+Here is an illustration, by Jon Loeliger.  Both commit nodes B
+and C are parents of commit node A.  Parent commits are ordered
+left-to-right.
+
+........................................
+G   H   I   J

+    I = F^   = B^3^    = A^^3^
+    J = F^2  = B^3^2   = A^^3^2
+
+
+SPECIFYING RANGES
+-----------------
+
+History traversing commands such as 'git log' operate on a set
+of commits, not just a single commit.  To these commands,
+specifying a single revision with the notation described in the
+previous section means the set of commits reachable from that
+commit, following the commit ancestry chain.
+
+To exclude commits reachable from a commit, a prefix `{caret}`
+notation is used.  E.g. `{caret}r1 r2` means commits reachable
+from `r2` but exclude the ones reachable from `r1`.
+
+This set operation appears so often that there is a shorthand
+for it.  When you have two commits `r1` and `r2` (named according
+to the syntax explained in SPECIFYING REVISIONS above), you can ask
+for commits that are reachable from r2 excluding those that are reachable
+from r1 by `{caret}r1 r2` and it can be written as `r1..r2`.
+
+A similar notation `r1\...r2` is called symmetric difference
+of `r1` and `r2` and is defined as
+`r1 r2 --not $(git merge-base --all r1 r2)`.
+It is the set of commits that are reachable from either one of
+`r1` or `r2` but not from both.
+
+Two other shorthands for naming a set that is formed by a commit
+and its parent commits exist.  The `r1{caret}@` notation means all
+parents of `r1`.  `r1{caret}!` includes commit `r1` but excludes
+all of its parents.
+
+Here are a handful of examples:
+
+   D                G H D
+   D F              G H I J D F
+   ^G D             H D
+   ^D B             E I J F B
+   B...C            G H D E B C
+   ^D B C           E I J F B C
+   C^@              I J F
+   F^! D            G H D F

+merge API
+=========
+
+The merge API helps a program to reconcile two competing sets of
+improvements to some files (e.g., unregistered changes from the work
+tree versus changes involved in switching to a new branch), reporting
+conflicts if found.  The library called through this API is
+responsible for a few things.
+
+ * determining which trees to merge (recursive ancestor consolidation);
+
+ * lining up corresponding files in the trees to be merged (rename
+   detection, subtree shifting), reporting edge cases like add/add
+   and rename/rename conflicts to the user;
+
+ * performing a three-way merge of corresponding files, taking
+   path-specific merge drivers (specified in `.gitattributes`)
+   into account.
+
+Data structures
+---------------
+
+* `mmbuffer_t`, `mmfile_t`
+
+These store data usable for use by the xdiff backend, for writing and
+for reading, respectively.  See `xdiff/xdiff.h` for the definitions
+and `diff.c` for examples.
+
+* `struct ll_merge_options`
+
+This describes the set of options the calling program wants to affect
+the operation of a low-level (single file) merge.  Some options:
+
+`virtual_ancestor`::
+       Behave as though this were part of a merge between common
+       ancestors in a recursive merge.
+       If a helper program is specified by the
+       `[merge "<driver>"] recursive` configuration, it will
+       be used (see linkgit:gitattributes[5]).
+
+`variant`::
+       Resolve local conflicts automatically in favor
+       of one side or the other (as in 'git merge-file'
+       `--ours`/`--theirs`/`--union`).  Can be `0`,
+       `XDL_MERGE_FAVOR_OURS`, `XDL_MERGE_FAVOR_THEIRS`, or
+       `XDL_MERGE_FAVOR_UNION`.
+
+`renormalize`::
+       Resmudge and clean the "base", "theirs" and "ours" files
+       before merging.  Use this when the merge is likely to have
+       overlapped with a change in smudge/clean or end-of-line
+       normalization rules.
+
+Low-level (single file) merge
+-----------------------------
+
+`ll_merge`::
+
+       Perform a three-way single-file merge in core.  This is
+       a thin wrapper around `xdl_merge` that takes the path and
+       any merge backend specified in `.gitattributes` or
+       `.git/info/attributes` into account.  Returns 0 for a
+       clean merge.
+
+Calling sequence:
+
+* Prepare a `struct ll_merge_options` to record options.
+  If you have no special requests, skip this and pass `NULL`
+  as the `opts` parameter to use the default options.
+
+* Allocate an mmbuffer_t variable for the result.
+
+* Allocate and fill variables with the file's original content
+  and two modified versions (using `read_mmfile`, for example).
+
+* Call `ll_merge()`.
+
+* Read the merged content from `result_buf.ptr` and `result_buf.size`.
+
+* Release buffers when finished.  A simple
+  `free(ancestor.ptr); free(ours.ptr); free(theirs.ptr);
+  free(result_buf.ptr);` will do.
+
+If the modifications do not merge cleanly, `ll_merge` will return a
+nonzero value and `result_buf` will generally include a description of
+the conflict bracketed by markers such as the traditional `<<<<<<<`
+and `>>>>>>>`.
+
+The `ancestor_label`, `our_label`, and `their_label` parameters are
+used to label the different sides of a conflict if the merge driver
+supports this.
+
+Everything else
+---------------
+
+Talk about <merge-recursive.h> and merge_file():
+
+ - merge_trees() to merge with rename detection
+ - merge_recursive() for ancestor consolidation
+ - try_merge_command() for other strategies
+ - conflict format
+ - merge options

+sigchain API
+============
+
+Code often wants to set a signal handler to clean up temporary files or
+other work-in-progress when we die unexpectedly. For multiple pieces of
+code to do this without conflicting, each piece of code must remember
+the old value of the handler and restore it either when:
+
+  1. The work-in-progress is finished, and the handler is no longer
+     necessary. The handler should revert to the original behavior
+     (either another handler, SIG_DFL, or SIG_IGN).
+
+  2. The signal is received. We should then do our cleanup, then chain
+     to the next handler (or die if it is SIG_DFL).
+
+Sigchain is a tiny library for keeping a stack of handlers. Your handler
+and installation code should look something like:
+
+------------------------------------------
+  void clean_foo_on_signal(int sig)
+  {
+         clean_foo();
+         sigchain_pop(sig);
+         raise(sig);
+  }
+
+  void other_func()
+  {
+         sigchain_push_common(clean_foo_on_signal);
+         mess_up_foo();
+         clean_foo();
+  }
+------------------------------------------
+
+Handlers are given the typdef of sigchain_fun. This is the same type
+that is given to signal() or sigaction(). It is perfectly reasonable to
+push SIG_DFL or SIG_IGN onto the stack.
+
+You can sigchain_push and sigchain_pop individual signals. For
+convenience, sigchain_push_common will push the handler onto the stack
+for many common signals.

+   The former two functions operate on STRING with length LENGTH,

+
+   re_match() matches the compiled pattern in BUFP against the string,

+   re_search() first tries matching at index START, then it tries to match

+   concerned.
+

+   and all groups is stroed in REGS.  (For the "_2" variants, the offsets are

+   strings.)

+Sample programs callable through git-shell.  Place a directory named
+'git-shell-commands' in the home directory of a user whose shell is
+git-shell.  Then anyone logging in as that user will be able to run
+executables in the 'git-shell-commands' directory.
+
+Provided commands:
+
+help: Prints out the names of available commands.  When run
+interactively, git-shell will automatically run 'help' on startup,
+provided it exists.
+
+list: Displays any bare repository whose name ends with ".git" under
+user's home directory.  No other git repositories are visible,
+although they might be clonable through git-shell.  'list' is designed
+to minimize the number of calls to git that must be made in finding
+available repositories; if your setup has additional repositories that
+should be user-discoverable, you may wish to modify 'list'
+accordingly.

+=========
+
+NAME
+----
+svn-fe - convert an SVN "dumpfile" to a fast-import stream
+
+SYNOPSIS
+--------
+svnadmin dump --incremental REPO | svn-fe [url] | git fast-import
+
+DESCRIPTION
+-----------
+
+Converts a Subversion dumpfile into input suitable for
+git-fast-import(1) and similar importers. REPO is a path to a
+Subversion repository mirrored on the local disk. Remote Subversion
+repositories can be mirrored on local disk using the `svnsync`
+command.
+
+INPUT FORMAT
+------------
+Subversion's repository dump format is documented in full in
+`notes/dump-load-format.txt` from the Subversion source tree.
+Files in this format can be generated using the 'svnadmin dump' or
+'svk admin dump' command.
+
+Dumps produced with 'svnadmin dump --deltas' (dumpfile format v3)
+are not supported.
+
+OUTPUT FORMAT
+-------------
+The fast-import format is documented by the git-fast-import(1)
+manual page.
+
+NOTES
+-----
+Subversion dumps do not record a separate author and committer for
+each revision, nor a separate display name and email address for
+each author.  Like git-svn(1), 'svn-fe' will use the name
+
+---------
+user <user@UUID>
+---------
+
+as committer, where 'user' is the value of the `svn:author` property
+and 'UUID' the repository's identifier.
+
+To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
+the end of each commit log message if passed an url on the command
+line.  This line has the form `git-svn-id: URL@REVNO UUID`.
+
+The resulting repository will generally require further processing
+to put each project in its own repository and to separate the history
+of each branch.  The 'git filter-branch --subdirectory-filter' command
+may be useful for this purpose.
+
+BUGS
+----
+Empty directories and unknown properties are silently discarded.
+
+The exit status does not reflect whether an error was detected.

    consistently when command line arguments --verbose (or -v),
    --debug (or -d), and --immediate (or -i) is given.
 
+Do's, don'ts & things to keep in mind
+-------------------------------------
+
+Here are a few examples of things you probably should and shouldn't do
+when writing tests.
+
+Do:
+
+ - Put all code inside test_expect_success and other assertions.
+
+   Even code that isn't a test per se, but merely some setup code
+   should be inside a test assertion.
+
+ - Chain your test assertions
+
+   Write test code like this:
+
+       git merge foo &&
+       git push bar &&
+       test ...
+
+   Instead of:
+
+       git merge hla
+       git push gh
+       test ...
+
+   That way all of the commands in your tests will succeed or fail. If
+   you must ignore the return value of something, consider using a
+   helper function (e.g. use sane_unset instead of unset, in order
+   to avoid unportable return value for unsetting a variable that was
+   already unset), or prepending the command with test_might_fail or
+   test_must_fail.
+
+ - Check the test coverage for your tests. See the "Test coverage"
+   below.
+
+   Don't blindly follow test coverage metrics, they're a good way to
+   spot if you've missed something. If a new function you added
+   doesn't have any coverage you're probably doing something wrong,
+   but having 100% coverage doesn't necessarily mean that you tested
+   everything.
+
+   Tests that are likely to smoke out future regressions are better
+   than tests that just inflate the coverage metrics.
+
+Don't:
+
+ - exit() within a <script> part.
+
+   The harness will catch this as a programming error of the test.
+   Use test_done instead if you need to stop the tests early (see
+   "Skipping tests" below).
+
+ - Break the TAP output
+
+   The raw output from your test may be interpreted by a TAP harness. TAP
+   harnesses will ignore everything they don't know about, but don't step
+   on their toes in these areas:
+
+   - Don't print lines like "$x..$y" where $x and $y are integers.
+
+   - Don't print lines that begin with "ok" or "not ok".
+
+   TAP harnesses expect a line that begins with either "ok" and "not
+   ok" to signal a test passed or failed (and our harness already
+   produces such lines), so your script shouldn't emit such lines to
+   their output.
+
+   You can glean some further possible issues from the TAP grammar
+   (see http://search.cpan.org/perldoc?TAP::Parser::Grammar#TAP_Grammar)
+   but the best indication is to just run the tests with prove(1),
+   it'll complain if anything is amiss.
+
+Keep in mind:
+
+ - Inside <script> part, the standard output and standard error
+   streams are discarded, and the test harness only reports "ok" or
+   "not ok" to the end user running the tests. Under --verbose, they
+   are shown to help debugging the tests.
+
+
+Skipping tests
+--------------
+
+If you need to skip tests you should do so be using the three-arg form
+of the test_* functions (see the "Test harness library" section
+below), e.g.:
+
+    test_expect_success PERL 'I need Perl' "
+        '$PERL_PATH' -e 'hlagh() if unf_unf()'
+    "
+
+The advantage of skipping tests like this is that platforms that don't
+have the PERL and other optional dependencies get an indication of how
+many tests they're missing.
+
+If the test code is too hairy for that (i.e. does a lot of setup work
+outside test assertions) you can also skip all remaining tests by
+setting skip_all and immediately call test_done:
+
+       if ! test_have_prereq PERL
+       then
+           skip_all='skipping perl interface tests, perl not available'
+           test_done
+       fi
+
+The string you give to skip_all will be used as an explanation for why
+the test was skipped.

+
+Test coverage
+-------------
+
+You can use the coverage tests to find code paths that are not being
+used or properly exercised yet.
+
+To do that, run the coverage target at the top-level (not in the t/
+directory):
+
+    make coverage
+
+That'll compile Git with GCC's coverage arguments, and generate a test
+report with gcov after the tests finish. Running the coverage tests
+can take a while, since running the tests in parallel is incompatible
+with GCC's coverage mode.
+
+After the tests have run you can generate a list of untested
+functions:
+
+    make coverage-untested-functions
+
+You can also generate a detailed per-file HTML report using the
+Devel::Cover module. To install it do:
+
+   # On Debian or Ubuntu:
+   sudo aptitude install libdevel-cover-perl
+
+   # From the CPAN with cpanminus
+   curl -L http://cpanmin.us | perl - --sudo --self-upgrade
+   cpanm --sudo Devel::Cover
+
+Then, at the top-level:
+
+    make cover_db_html
+
+That'll generate a detailed cover report in the "cover_db_html"
+directory, which you can then copy to a webserver, or inspect locally
+in a browser.
+
+Smoke testing
+-------------
+
+The Git test suite has support for smoke testing. Smoke testing is
+when you submit the results of a test run to a central server for
+analysis and aggregation.
+
+Running a smoke tester is an easy and valuable way of contributing to
+Git development, particularly if you have access to an uncommon OS on
+obscure hardware.
+
+After building Git you can generate a smoke report like this in the
+"t" directory:
+
+    make clean smoke
+
+You can also pass arguments via the environment. This should make it
+faster:
+
+    GIT_TEST_OPTS='--root=/dev/shm' TEST_JOBS=10 make clean smoke
+
+The "smoke" target will run the Git test suite with Perl's
+"TAP::Harness" module, and package up the results in a .tar.gz archive
+with "TAP::Harness::Archive". The former is included with Perl v5.10.1
+or later, but you'll need to install the latter from the CPAN. See the
+"Test coverage" section above for how you might do that.
+
+Once the "smoke" target finishes you'll see a message like this:
+
+    TAP Archive created at <path to git>/t/test-results/git-smoke.tar.gz
+
+To upload the smoke report you need to have curl(1) installed, then
+do:
+
+    make smoke_report
+
+To upload the report anonymously. Hopefully that'll return something
+like "Reported #7 added.".
+
+If you're going to be uploading reports frequently please request a
+user account by E-Mailing gitsmoke@v.nix.is. Once you have a username
+and password you'll be able to do:
+
+    SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> make smoke_report
+
+You can also add an additional comment to attach to the report, and/or
+a comma separated list of tags:
+
+    SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> \
+        SMOKE_COMMENT=<comment> SMOKE_TAGS=<tags> \
+        make smoke_report
+
+Once the report is uploaded it'll be made available at
+http://smoke.git.nix.is, here's an overview of Recent Smoke Reports
+for Git:
+
+    http://smoke.git.nix.is/app/projects/smoke_reports/1
+
+The reports will also be mirrored to GitHub every few hours:
+
+    http://github.com/gitsmoke/smoke-reports
+
+The Smolder SQLite database is also mirrored and made available for
+download:
+
+    http://github.com/gitsmoke/smoke-database
+
+Note that the database includes hashed (with crypt()) user passwords
+and E-Mail addresses. Don't use a valuable password for the smoke
+service if you have an account, or an E-Mail address you don't want to
+be publicly known. The user accounts are just meant to be convenient
+labels, they're not meant to be secure.

+           Hope, he says, cherishes the soul of him who lives in
+           justice and holiness and is the nurse of his age and the
+           companion of his journey;--hope which is mightiest to sway
+           the restless soul of man.
+
+       How admirable are his words!  And the great blessing of riches, I do
+       not say to every man, but to a good man, is, that he has had no
+       occasion to deceive or to defraud others, either intentionally or
+       unintentionally; and when he departs to the world below he is not in
+       any apprehension about offerings due to the gods or debts which he owes
+       to men.  Now to this peace of mind the possession of wealth greatly
+       contributes; and therefore I say, that, setting one thing against
+       another, of the many advantages which wealth has to give, to a man of
+       sense this is in my opinion the greatest.
+
+       Well said, Cephalus, I replied; but as concerning justice, what is
+       it?--to speak the truth and to pay your debts--no more than this?  And
+       even to this are there not exceptions?  Suppose that a friend when in
+       his right mind has deposited arms with me and he asks for them when he
+       is not in his right mind, ought I to give them back to him?  No one
+       would say that I ought or that I should be right in doing so, any more
+       than they would say that I ought always to speak the truth to one who
+       is in his condition.
+
+       You are quite right, he replied.
+
+       But then, I said, speaking the truth and paying your debts is not a
+       correct definition of justice.
+
+       CEPHALUS - SOCRATES - POLEMARCHUS
+
+       Quite correct, Socrates, if Simonides is to be believed, said
+       Polemarchus interposing.
+
+       I fear, said Cephalus, that I must go now, for I have to look after the
+       sacrifices, and I hand over the argument to Polemarchus and the company.

+line_buffer API
+===============
+
+The line_buffer library provides a convenient interface for
+mostly-line-oriented input.
+
+Each line is not permitted to exceed 10000 bytes.  The provided
+functions are not thread-safe or async-signal-safe, and like
+`fgets()`, they generally do not function correctly if interrupted
+by a signal without SA_RESTART set.
+
+Calling sequence
+----------------
+
+The calling program:
+
+ - specifies a file to read with `buffer_init`
+ - processes input with `buffer_read_line`, `buffer_read_string`,
+   `buffer_skip_bytes`, and `buffer_copy_bytes`
+ - closes the file with `buffer_deinit`, perhaps to start over and
+   read another file.
+
+Before exiting, the caller can use `buffer_reset` to deallocate
+resources for the benefit of profiling tools.
+
+Functions
+---------
+
+`buffer_init`::
+       Open the named file for input.  If filename is NULL,
+       start reading from stdin.  On failure, returns -1 (with
+       errno indicating the nature of the failure).
+
+`buffer_deinit`::
+       Stop reading from the current file (closing it unless
+       it was stdin).  Returns nonzero if `fclose` fails or
+       the error indicator was set.
+
+`buffer_read_line`::
+       Read a line and strip off the trailing newline.
+       On failure or end of file, returns NULL.
+
+`buffer_read_string`::
+       Read `len` characters of input or up to the end of the
+       file, whichever comes first.  Returns NULL on error.
+       Returns whatever characters were read (possibly "")
+       for end of file.
+
+`buffer_copy_bytes`::
+       Read `len` bytes of input and dump them to the standard output
+       stream.  Returns early for error or end of file.
+
+`buffer_skip_bytes`::
+       Discards `len` bytes from the input stream (stopping early
+       if necessary because of an error or eof).
+
+`buffer_reset`::
+       Deallocates non-static buffers.

+string_pool API
+===============
+
+The string_pool API provides facilities for replacing strings
+with integer keys that can be more easily compared and stored.
+The facilities are designed so that one could teach Git without
+too much trouble to store the information needed for these keys to
+remain valid over multiple executions.
+
+Functions
+---------
+
+pool_intern::
+       Include a string in the string pool and get its key.
+       If that string is already in the pool, retrieves its
+       existing key.
+
+pool_fetch::
+       Retrieve the string associated to a given key.
+
+pool_tok_r::
+       Extract the key of the next token from a string.
+       Interface mimics strtok_r.
+
+pool_print_seq::
+       Print a sequence of strings named by key to a file, using the
+       specified delimiter to separate them.
+
+       If NULL (key ~0) appears in the sequence, the sequence ends
+       early.
+
+pool_tok_seq::
+       Split a string into tokens, storing the keys of segments
+       into a caller-provided array.
+
+       Unless sz is 0, the array will always be ~0-terminated.
+       If there is not enough room for all the tokens, the
+       array holds as many tokens as fit in the entries before
+       the terminating ~0.  Return value is the index after the
+       last token, or sz if the tokens did not fit.
+
+pool_reset::
+       Deallocate storage for the string pool.

+Motivation
+==========
+
+Treaps provide a memory-efficient binary search tree structure.
+Insertion/deletion/search are about as about as fast in the average
+case as red-black trees and the chances of worst-case behavior are
+vanishingly small, thanks to (pseudo-)randomness.  The bad worst-case
+behavior is a small price to pay, given that treaps are much simpler
+to implement.
+
+API
+===
+
+The trp API generates a data structure and functions to handle a
+large growing set of objects stored in a pool.
+
+The caller:
+
+. Specifies parameters for the generated functions with the
+  trp_gen(static, foo_, ...) macro.
+
+. Allocates a `struct trp_root` variable and sets it to {~0}.
+
+. Adds new nodes to the set using `foo_insert`.  Any pointers
+  to existing nodes cannot be relied upon any more, so the caller
+  might retrieve them anew with `foo_pointer`.
+
+. Can find a specific item in the set using `foo_search`.
+
+. Can iterate over items in the set using `foo_first` and `foo_next`.
+
+. Can remove an item from the set using `foo_remove`.
+
+Example:
+
+----
+struct ex_node {
+       const char *s;
+       struct trp_node ex_link;
+};
+static struct trp_root ex_base = {~0};
+obj_pool_gen(ex, struct ex_node, 4096);
+trp_gen(static, ex_, struct ex_node, ex_link, ex, strcmp)
+struct ex_node *item;
+
+item = ex_pointer(ex_alloc(1));
+item->s = "hello";
+ex_insert(&ex_base, item);
+item = ex_pointer(ex_alloc(1));
+item->s = "goodbye";
+ex_insert(&ex_base, item);
+for (item = ex_first(&ex_base); item; item = ex_next(&ex_base, item))
+       printf("%s\n", item->s);
+----
+
+Functions
+---------
+
+trp_gen(attr, foo_, node_type, link_field, pool, cmp)::
+
+       Generate a type-specific treap implementation.
++
+. The storage class for generated functions will be 'attr' (e.g., `static`).
+. Generated function names are prefixed with 'foo_' (e.g., `treap_`).
+. Treap nodes will be of type 'node_type' (e.g., `struct treap_node`).
+  This type must be a struct with at least one `struct trp_node` field
+  to point to its children.
+. The field used to access child nodes will be 'link_field'.
+. All treap nodes must lie in the 'pool' object pool.
+. Treap nodes must be totally ordered by the 'cmp' relation, with the
+  following prototype:
++
+int (*cmp)(node_type \*a, node_type \*b)
++
+and returning a value less than, equal to, or greater than zero
+according to the result of comparison.
+
+node_type {asterisk}foo_insert(struct trp_root *treap, node_type \*node)::
+
+       Insert node into treap.  If inserted multiple times,
+       a node will appear in the treap multiple times.
++
+The return value is the address of the node within the treap,
+which might differ from `node` if `pool_alloc` had to call
+`realloc` to expand the pool.
+
+void foo_remove(struct trp_root *treap, node_type \*node)::
+
+       Remove node from treap.  Caller must ensure node is
+       present in treap before using this function.
+
+node_type *foo_search(struct trp_root \*treap, node_type \*key)::
+
+       Search for a node that matches key.  If no match is found,
+       result is NULL.
+
+node_type *foo_nsearch(struct trp_root \*treap, node_type \*key)::
+
+       Like `foo_search`, but if if the key is missing return what
+       would be key's successor, were key in treap (NULL if no
+       successor).
+
+node_type *foo_first(struct trp_root \*treap)::
+
+       Find the first item from the treap, in sorted order.
+
+node_type *foo_next(struct trp_root \*treap, node_type \*node)::
+
+       Find the next item.
