Subject: [WIP PATCH] Add a skeleton RA SVN client
Date: Wed, 2 Jun 2010 15:08:36 +0200 [thread overview]
Message-ID: <1275484116-32520-2-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1275484116-32520-1-git-send-email-artagnon@gmail.com>
The SVN client uses the RA API to connect to a remote server and
replay revisions. In future, it will dump the data in every revision
to stdout in dumpfile format (hopefully) without resorting to the FS
API and svn_repos_dump_fs2.
