commit 0eb2649bdeca7908c0d399321a21ffe189e4b8f6
Author: Matthew Barnes <mbarnes redhat com>
Date: Tue Dec 15 22:00:45 2009 -0500
Introduce EMailBackend into libevolution-mail.
EMailBackend is an abstract subclass of EShellBackend that handles
online and offline modes and application shutdown. Placing this in
the shared mail library allows Anjal to reuse it. Evolution's mail
module further extends this class as EMailShellBackend.
