'''integration with Subversion repositories

This extension allows Mercurial to act as a Subversion client, for
fast incremental, bidirectional updates.

It is *not* ready yet for production use. You should only be using
this if you're ready to hack on it, and go diving into the internals
of Mercurial and/or Subversion.

Before using hgsubversion, it is *strongly* encouraged to run the
automated tests. See `README' in the hgsubversion directory for
details.
