This patch adds a post-receive hook to lib/git, which can be used to
update Patchwork following a push to the Git repository.

Surely, it can be improved. One thing to do would be to export the state
map to git-config somehow.

Hi Martin,

Just going doing some patchwork updates, and noticed that you've licenced this 
file under the Artistic Licence. Would you be prepared to make these 
contributions under the GPL?

Regards,


Jeremy

Begrudgedly, as I consider the GPL non-free, if you need it… yes.
