Nope - always separate.

Erm not really - that I know of. There is this thread which I use for
reference:

This PPD doesn't contain any info about what modules it provides
(ideally, it should have a provide tags for all modules in bioperl) or
the dependencies via the require tag.

I didn't have an automated way of making it. Previously, the output of
"make ppd" used PREREQ_PM from makefile.pl to create PPM3 dependency
tags for all modules in PREREQ_PM. I just modified the tags to REQUIRE
and added '::' to the end of modules that didn't natively have one. This
should all be detailed in the above in - here again for convenience:
http://aspn.activestate.com/ASPN/Mail/Message/ppm/3243428

There must be an automated way to generate the PPM4 compatible PPDs - I
think there is a way to generate one from the CPAN distribution. I think
this might be the way ActiveState does it?
