I didn't say anything about 2 files.  I said I prefered a parts list
in a single option in combination with a standard buildout versions
section.  There are a number of reasons for this:

- We'll need the versions section to consume the KGS.  That is, given
a KGS, you'll often want to use the versions in other buildouts to
limit them to the known good configuration.

- I think a parts list in an option will be easier to control.  For
example, you will be able to use the standard buildout option
incrementing and decrementating machinery to modify it.

- After using it for a day, I find the controlled-packages syntax to
be a bit heavy.  Of course, it didn't help that I still had to create
a versions list.

- The parts section and versions section could be specified in a
single file, so the "gesture" for using them could be pretty simple.
