Fine with me. The date should probably be the build date in a first step. 
GHC'S build system is currently trying to be clever by asking darcs about the 
latest change and using that date, but this a bit of a hack at the moment and 
doesn't e.g. take into account the packages IIRC.

I think a file containing lines like

   core base ???
   core Cabal ???
   extra OpenGL ???
   extra http://www.cs.york.ac.uk/fp/darcs/polyparse ???
   ...

might do the trick, with the first column describing the status of the package 
and the second column the place to get the bleeding edge version of it 
(non-http: repositories can be calculated via the repository for hugs itself, 
see the darcs-all script for GHC, nhc98 lacks this feature). The tricky part 
is the third column, describing the released version to use for release 
builds. I guess we should use hackage somehow, but currently I fail to see 
how... :-( Any suggestions?
