Notice I admitted that I couldn't believe I said that CVS was easier
than GIT there too.  :-)

Actually it is pretty easy with git too.  I ended up doing it this way:

#!/bin/sh
while read oldrev newrev refname; do
  echo $oldrev $newrev $refname | /usr/local/bin/git-post-receive-hook
  echo $oldrev $newrev $refname | hooks/post-receive-mail-local
done
exit 0

That will easily expand to more hooks if needed.  Not terrible.  Just
a problem if you don't realize that it operates that way and try to
use "run-parts" as would be the obvious thing. :-)

That is the more simple way to do it.  I think most people would like
it better that way.  I don't know why git's post-receive uses stdin.
I think that is definitely less nice.  But not the end of the world
either.

I am very happy to see the wiki documentation back online again!
