 'git-svn' <command> [options] [arguments]
 
 DESCRIPTION
 -----------
-git-svn is a simple conduit for changesets between a single Subversion
-branch and git. It is not to be confused with gitlink:git-svnimport[1].
-They were designed with very different goals in mind.

+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.  git-svnimport is designed
-for read-only operation on repositories that match a particular layout
-(albeit the recommended one by SVN developers).
+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; but it cannot (yet) automatically detect new
+branches and tags like git-svnimport does.
 
-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 mostly 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.
+git-svn is especially useful when it comes to tracking repositories
+not organized in the way Subversion developers recommend (trunk,
+branches, tags directories).
