Post-commit hook recipes?

[Peter Ruprecht]

Hi,

I've been looking for a collection of example post-commit hook scripts 
without much luck.  If anyone knows of a good one, can you please point 
me in the right direction?  If I can avoid reinventing some wheels, that 
would be great.

In particular, at the moment I'm looking for a post-commit hook that 
will email *only* the user who made the previous commit.

Thanks!
Peter Ruprecht
