+Contributed Software
+
+Although these pieces are available as part of the official git
+source tree, they are in somewhat different status. The
+intention is to keep interesting tools around git here, maybe
+even experimental ones, to give users an easier access to them,
+and to give tools wider exposure, so that they can be improved
+faster.
+
+I am not expecting to touch these myself that much. As far as
+my day-to-day operation is concerned, these subdirectories are
+owned by their respective primary authors. I am willing to help
+if users of these components and the contrib/ subtree "owners"
+have technical/design issues to resolve, but the initiative to
+fix and/or enhance things _must_ be on the side of the subtree
+owners. IOW, I won't be actively looking for bugs and rooms for
+enhancements in them as the git maintainer -- I may only do so
+just as one of the users when I want to scratch my own itch. If
+you have patches to things in contrib/ area, the patch should be
+first sent to the primary author, and then the primary author
+should ack and forward it to me (git pull request is nicer).
+This is the same way as how I have been treating gitk, and to a
+lesser degree various foreign SCM interfaces, so you know the
+drill.
+
+I expect that things that start their life in the contrib/ area
+to graduate out of contrib/ once they mature, either by becoming
+projects on their own, or moving to the toplevel directory. On
+the other hand, I expect I'll be proposing removal of disused
+and inactive ones from time to time.
+
+If you have new things to add to this area, please first propose
+it on the git mailing list, and after a list discussion proves
+there are some general interests (it does not have to be a
+list-wide consensus for a tool targeted to a relatively narrow
+audience -- for example I do not work with projects whose
+upstream is svn, so I have no use for git-svn myself, but it is
+of general interest for people who need to interoperate with SVN
+repositories in a way git-svn works better than git-svnimport),
+submit a patch to create a subdirectory of contrib/ and put your
+stuff there.

+NAME
+----
+git-svn - bidirectional operation between a single Subversion branch and git
+
+SYNOPSIS
+--------
+'git-svn' <command> [options] [arguments]
+
+DESCRIPTION
+-----------
+git-svn is a simple conduit for changesets between a single Subversion
+branch and git.
+
+git-svn is not to be confused with git-svnimport. The were designed
+with very different goals in mind.
+
+git-svn is designed for an individual developer who wants a
+bidirectional flow of changesets between a single branch in Subversion
+and an arbitrary number of branches in git. git-svnimport is designed
+for read-only operation on repositories that match a particular layout
+(albeit the recommended one by SVN developers).
+
+For importing svn, git-svnimport is potentially more powerful when
+operating on repositories organized under the recommended
+trunk/branch/tags structure, and should be faster, too.
+
+git-svn completely ignores the very limited view of branching that
+Subversion has. This allows git-svn to be much easier to use,
+especially on repositories that are not organized in a manner that
+git-svnimport is designed for.
+
+COMMANDS
+--------
+init::
+ Creates an empty git repository with additional metadata
+ directories for git-svn. The SVN_URL must be specified
+ at this point.
+
+fetch::
+ Fetch unfetched revisions from the SVN_URL we are tracking.
+ refs/heads/git-svn-HEAD will be updated to the latest revision.
+
+commit::
+ Commit specified commit or tree objects to SVN. This relies on
+ your imported fetch data being up-to-date. This makes
+ absolutely no attempts to do patching when committing to SVN, it
+ simply overwrites files with those specified in the tree or
+ commit. All merging is assumed to have taken place
+ independently of git-svn functions.
+
+rebuild::
+ Not a part of daily usage, but this is a useful command if
+ you've just cloned a repository (using git-clone) that was
+ tracked with git-svn. Unfortunately, git-clone does not clone
+ git-svn metadata and the svn working tree that git-svn uses for
+ its operations. This rebuilds the metadata so git-svn can
+ resume fetch operations. SVN_URL may be optionally specified if
+ the directory/repository you're tracking has moved or changed
+ protocols.
+
+OPTIONS
+-------
+-r <ARG>::
+--revision <ARG>::
+ Only used with the 'fetch' command.
+
+ Takes any valid -r<argument> svn would accept and passes it
+ directly to svn. -r<ARG1>:<ARG2> ranges and "{" DATE "}" syntax
+ is also supported. This is passed directly to svn, see svn
+ documentation for more details.
+
+ This can allow you to make partial mirrors when running fetch.
+
+-::
+--stdin::
+ Only used with the 'commit' command.
+
+ Read a list of commits from stdin and commit them in reverse
+ order. Only the leading sha1 is read from each line, so
+ git-rev-list --pretty=oneline output can be used.
+
+--rmdir::
+ Only used with the 'commit' command.
+
+ Remove directories from the SVN tree if there are no files left
+ behind. SVN can version empty directories, and they are not
+ removed by default if there are no files left in them. git
+ cannot version empty directories. Enabling this flag will make
+ the commit to SVN act like git.
+
+-e::
+--edit::
+ Only used with the 'commit' command.
+
+ Edit the commit message before committing to SVN. This is off by
+ default for objects that are commits, and forced on when committing
+ tree objects.
+
+COMPATIBILITY OPTIONS
+---------------------
+--no-ignore-externals::
+ Only used with the 'fetch' and 'rebuild' command.
+
+ By default, git-svn passes --ignore-externals to svn to avoid
+ fetching svn:external trees into git. Pass this flag to enable
+ externals tracking directly via git.
+
+ Versions of svn that do not support --ignore-externals are
+ automatically detected and this flag will be automatically
+ enabled for them.
+
+ Otherwise, do not enable this flag unless you know what you're
+ doing.
+
+--no-stop-on-copy::
+ Only used with the 'fetch' command.
+
+ By default, git-svn passes --stop-on-copy to avoid dealing with
+ the copied/renamed branch directory problem entirely. A
+ copied/renamed branch is the result of a <SVN_URL> being created
+ in the past from a different source. These are problematic to
+ deal with even when working purely with svn if you work inside
+ subdirectories.
+
+ Do not use this flag unless you know exactly what you're getting
+ yourself into. You have been warned.
+
+Examples
+~~~~~~~~
+
+Tracking and contributing to an Subversion managed-project:
+
+# Initialize a tree (like git init-db)::
+ git-svn init http://svn.foo.org/project/trunk
+# Fetch remote revisions::
+ git-svn fetch
+# Create your own branch to hack on::
+ git checkout -b my-branch git-svn-HEAD
+# Commit only the git commits you want to SVN::
+ git-svn commit <tree-ish> [<tree-ish_2> ...]
+# Commit all the git commits from my-branch that don't exist in SVN::
+ git rev-list --pretty=oneline git-svn-HEAD..my-branch | git-svn commit
+# Something is committed to SVN, pull the latest into your branch::
+ git-svn fetch && git pull . git-svn-HEAD
+
+DESIGN PHILOSOPHY
+-----------------
+Merge tracking in Subversion is lacking and doing branched development
+with Subversion is cumbersome as a result. git-svn completely forgoes
+any automated merge/branch tracking on the Subversion side and leaves it
+entirely up to the user on the git side. It's simply not worth it to do
+a useful translation when the the original signal is weak.
+
+TRACKING MULTIPLE REPOSITORIES OR BRANCHES
+------------------------------------------
+This is for advanced users, most users should ignore this section.
+
+Because git-svn does not care about relationships between different
+branches or directories in a Subversion repository, git-svn has a simple
+hack to allow it to track an arbitrary number of related _or_ unrelated
+SVN repositories via one git repository. Simply set the GIT_SVN_ID
+environment variable to a name other other than "git-svn" (the default)
+and git-svn will ignore the contents of the $GIT_DIR/git-svn directory
+and instead do all of its work in $GIT_DIR/$GIT_SVN_ID for that
+invocation.
+
+ADDITIONAL FETCH ARGUMENTS
+--------------------------
+This is for advanced users, most users should ignore this section.
+
+Unfetched SVN revisions may be imported as children of existing commits
+by specifying additional arguments to 'fetch'. Additional parents may
+optionally be specified in the form of sha1 hex sums at the
+command-line. Unfetched SVN revisions may also be tied to particular
+git commits with the following syntax:
+
+ svn_revision_number=git_commit_sha1
+
+This allows you to tie unfetched SVN revision 375 to your current HEAD::
+
+ git-svn fetch 375=$(git-rev-parse HEAD)
+
+BUGS
+----
+If somebody commits a conflicting changeset to SVN at a bad moment
+(right before you commit) causing a conflict and your commit to fail,
+your svn working tree ($GIT_DIR/git-svn/tree) may be dirtied. The
+easiest thing to do is probably just to rm -rf $GIT_DIR/git-svn/tree and
+run 'rebuild'.
+
+We ignore all SVN properties except svn:executable. Too difficult to
+map them since we rely heavily on git write-tree being _exactly_ the
+same on both the SVN and git working trees and I prefer not to clutter
+working trees with metadata files.
+
+svn:keywords can't be ignored in Subversion (at least I don't know of
+a way to ignore them).

+################################################################
+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+ merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+ it is deleted. If you need to build on top of it to correct
+ earlier mistakes, a new topic branch is created by forking at
+ the tip of the "master". This is not strictly necessary, but
+ it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+ branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next". Young
+ topic branches can have stupid mistakes you would rather
+ clean up before publishing, and things that have not been
+ merged into other branches can be easily rebased without
+ affecting other people. But once it is published, you would
+ not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+ Then you can delete it. More importantly, you should not
+ build on top of it -- other people may already want to
+ change things related to the topic as patches against your
+ "master", so if you need further changes, it is better to
+ fork the topic (perhaps with the same name) afresh from the
+ tip of "master".
+
+Let's look at this example:
+
+ o---o---o---o---o---o---o---o---o---o "next"
+ / / / /
+ / a---a---b A / /
+ / / / /
+ / / c---c---c---c B /
+ / / / \ /
+ / / / b---b C \ /
+ / / / / \ /
+ ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished. It has been fully merged up to "master" and "next",
+ and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+ git-rev-list ^master ^topic next
+ git-rev-list ^master next
+
+ if these match, topic has not merged in next at all.
+
+To compute (2):
+
+ git-rev-list master..topic
+
+ if this is empty, it is fully merged to "master".
