Git commit mail (debian)

With the backported git 1.6 packages installed - to add mailing lists for commits/tags:

cd src/<project>.git/hooks
ln -s /usr/share/doc/git-core/contrib/hooks/post-receive-email post-receive
git config --add hooks.mailinglist "development@mailhost.tld"
git config --add hooks.announcelist "announce@mailhost.tld"
git config --add hooks.envelopesender "from_addr@host.tld"

Note that /usr/share/doc/git-core/contrib/hooks/post-receive-email must be executable - chmod a+x if you need to.
