buildout_versions is a fork of buildout.dumppickedversions

Try http://packages.python.org/buildout_versions/use.html

The basic problems solved:

- when un-pinned, non-developed packages are encountered, report the 
versions buildout ended up picking

- if a file is specified (which can be buildout.cfg), append those those 
un-pinned versions to the end of that file

- if a python version is specified, blow up if a different version is 
used to run buildout.

I reckon it should just be in the core.

cheers,

Chris
