From 0c696fe7f490fd3a85e405becf6323993dfb471d Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 9 Oct 2007 15:33:25 +0100 Subject: [PATCH] Support cvs via git-shell This adds cvs support to the git-shell; You can now give new users a restricted git-shell and they still can commit via git's cvs emulator. Note that either the gecos information must be accurate, or you must provide a $HOME/.gitconfig with the appropriate user credentials. Since the git-shell is too restricted to allow the user to do it (on purpose!), it is up to the administrator to take care of that. Based on an idea by Jan Wielemaker.
