Hi

Attached is a small hook for updates that are pushed into repo.
Right now it only checks the first line of the commit and expects
module: summary

I have not tested it at all

Comments ?

Thanks

#!/usr/bin/env python
# usage update.py <oldrev> <newrev>
# currently it only checks for first line of the commit message
# which should look like e.g
# uclibc: <pretty summary>
