Hi Philip.

Yes, it is called texlive.tlpdb and contains all information you need.,

I think I have explained this in several talks and articles in TUGboat.
But for you I do it again:
There are three levels of packages in TeX Live:
* normal packages (practically everying) indicated by the tlpdb
  	category Package
* collections (indicated by the package name "collection-???" *and*
  by the tlpdb key/value 
  	category Collection
* schemes (indicated by the package name "scheme-???" *and*
  by the tlpdb key/value
  	category scheme

"Schemes" are overlapping collections of TeX Live packages. They can
depend on "collections" and "packages".

"Collections" are non-overlapping collections of TeX Live packages,
they can depend on other "collections" and "packages", but it is 
guaranteed that the same package is *not* included in two different

(Note that I put quotes on purpose to distinguish between the
defined concepts in TeX Live, and general mathematical concepts)

That should give you most of the necessary information (besides the
rest of the tlpdb, like executes ...)
