""" repository class-based interface for hgsubversion Copyright (C) 2009, Dan Villiom Podlaski Christiansen <danchr@gmail.com> See parent package for licensing. Internally, Mercurial assumes that every single repository is a localrepository subclass: pull() is called on the instance pull *to*, but not the one pulled *from*. To work around this, we create two classes: - svnremoterepo for Subversion repositories, but it doesn't really do anything. - svnlocalrepo for local repositories which handles both operations on itself -- the local, hgsubversion-enabled clone -- and the remote repository. Decorators are used to distinguish and filter these operations from others.
