Agreed.

I hope so -- I've been going around in circles for years trying to find 
a light weight solution for building inter-dependent functions, modules, 
and/or distributions.  The idea for this distribution grew out of a 
solution Joe Brenner showed me (he has a massive PERL5LIB set by a 
script that crawls his development tree).

Yes -- arguments received by 'perl Makefile.PL' are passed through to 
the recursive 'perl Makefile.PL' invocations.  At this point, the only 
argument I am aware of is 'verbose' (per 'perldoc ExtUtils::MakeMaker):

Similarly, arguments to 'make' are passed through:

DSL?

Could you please describe the concept of the script and/or show an 
example of its use?
