Add initial hook support -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Add initial hook support This adds the basic hook code as well as pre and post-commit hooks. Argument passing is by environment variable key/value pairs so that extra data can be passed over time. File lists will generally not be passed to hooks as these can be extremely long (>1M). manifest hash: 45cf9bab432782c391bc9c1c048c84cc75d52740 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCwOukywK+sNU5EO8RAsVsAJ9QipR2aKRSSvoRNo+3If6JddUDkwCgkZrM KEmZpUOxhNHqezFVrHDRTjE= =aedm -----END PGP SIGNATURE-----
