source code control for audit userspace tools

[Tony Jones]

I brought this up on #audit but the conversation didn't go anywhere.

It would be nice if there could be some form of source code control for
the changes that occur between revisions of the userspace tools.

Is development internally to RedHat done using any form of source code
control?  Or is the development more ad-hoq?

Full public source code control would perhaps be beneficial in terms of
fostering community development.  Failing this,  just having the diffs 
per discret change included in each release would be very helpful.

Possible?

Thanks

Tony
