DESCRIPTION
-----------
-git-svn is a simple conduit for changesets between Subversion and git.
-It is not to be confused with linkgit:git-svnimport[1], which is
-read-only.
+'git-svn' is a simple conduit for changesets between Subversion and git.
+It provides a bidirectional flow of changes between a Subversion and a git
+repository.
-git-svn was originally 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. Since its inception,
-git-svn has gained the ability to track multiple branches in a manner
-similar to git-svnimport.
+'git-svn' can track a single Subversion branch simply by using a
+URL to the branch, follow branches laid out in the Subversion recommended
+method (trunk, branches, tags directories) with the --stdlayout option, or
+follow branches in any layout with the -T/-t/-b options (see options to
+'init' below, and also the 'clone' command).
-git-svn is especially useful when it comes to tracking repositories
-not organized in the way Subversion developers recommend (trunk,
-branches, tags directories).
+Once tracking a Subversion branch (with any of the above methods), the git
+repository can be updated from Subversion by the 'fetch' command and
+Subversion updated from git by the 'dcommit' command.
COMMANDS
--------
'init'::
Initializes an empty git repository with additional
- metadata directories for git-svn. The Subversion URL
+ metadata directories for 'git-svn'. The Subversion URL
may be specified as a command-line argument, or as full
URL arguments to -T/-t/-b. Optionally, the target
directory to operate on can be specified as a second
.git/config file may be specified as an optional command-line
argument.
+--localtime;;
+ Store Git commit times in the local timezone instead of UTC. This
+ makes 'git-log' (even without --date=local) show the same times
+ that `svn log` would in the local timezone.
+
+This doesn't interfere with interoperating with the Subversion
+repository you cloned from, but if you wish for your local Git
+repository to be able to interoperate with someone else's local Git
+repository, either don't use this option or you should both use it in
+the same local timezone.
+
+--ignore-paths=<regex>;;
+ This allows one to specify Perl regular expression that will
+ cause skipping of all matching paths from checkout from SVN.
+ Examples:
+
+ --ignore-paths="^doc" - skip "doc*" directory for every fetch.
+
+ --ignore-paths="^[^/]+/(?:branches|tags)" - skip "branches"
+ and "tags" of first level directories.
+
+ Regular expression is not persistent, you should specify
+ it every time when fetching.
+
'clone'::
Runs 'init' and 'fetch'. It will automatically create a
directory based on the basename of the URL passed to it;
This fetches revisions from the SVN parent of the current HEAD
and rebases the current (uncommitted to SVN) work against it.
-This works similarly to 'svn update' or 'git-pull' except that

Like 'git-rebase'; this requires that the working tree be clean

not there is a diff between SVN and head). This will create
a revision in SVN for each commit in git.

--no-rebase;;
After committing, do not rebase or reset.
+--commit-url <URL>;;
+ Commit to this SVN URL (the full path). This is intended to
+ allow existing git-svn repositories created with one transport
+ method (e.g. `svn://` or `http://` for anonymous read) to be
+ reused if a user is later given access to an alternate transport
+ method (e.g. `svn+ssh://` or `https://`) for commit.
+
