[PATCH] Using monotone-viz/git-viz with mercurial

From: Vincent Danjean <[e-mail]>

  monotone-viz is a small GTK+ application that visualizes monotone
ancestry graphs. Its home page is:
http://oandrieu.nerim.net/monotone-viz/
  As monotone and git are similar, the author adapted the 0.9 version to
display git ancestry graphs and call it git-viz. I cannot see any link
from the homepage, but looking in the archive of git ML, it can be found
here:
http://oandrieu.nerim.net/monotone-viz/git-viz-0.1.tar.gz

  I few days ago, I adapted it so that it works with the last versions
of git/cogito. Patches and package are available here:
http://dept-info.labri.fr/~danjean/deb.html#git-viz

  Today, I patched hgit so that it respects the output of git-diff-tree,
I added git-{diff-tree,cat-file,rev-list,rev-tree} that call hgit (2
lines scripts), and added the script 'hg-viz'.
  hg-viz create a .git directory and store the SHA1 of the tip in
.git/HEAD and then call my git-viz.
  All these modifications are in the attached patch.

  I try it in the mercurial repository. After applying the patch, you
just have to add the contrib directory in your PATH and call hg-viz.
  An example of what we can see is on my web page (probably not for a
long time) : http://dept-info.labri.fr/~danjean/temp/hg-viz.png
