The Debian packaging of cvm is maintained using dgit.  For the sake
of an efficient workflow, Debian modifications to the upstream
source are squashed into a single diff, rather than a series of
quilt patches.  To obtain a patch queue for package version
0.97-0.1:

    # apt-get install dgit
    % dgit clone cvm
    % cd foo
    % git log --oneline 0.97-0.1..debian/0.97 -- . ':!debian'
