This is a very valid point. We need to work on exposing the
dh-make-perl internals so that other things like cpan2dist can use it,
while not having to constantly update their stuff to keep in sync with
policy. I'd also like to push for dh-make-perl to be release normally
via CPAN. Currently though I'm scared of the codebase, as it's fairly
messy stuff. damyan is brave :-)

Indeed though, a good long term goal is figuring out a good pattern
for exposing the API, so we can upload them as normal modules via
CPAN, and so they can be used directly by cpan2dist instead of having
to roll their own stuff.

I think that has the best outcome for everyone, and the DhMakePerl.pm
is a good first step in that direction.
