[Module-build-general] Re: Recursive building

[Scott C. <ca...@cs...>]

Hello, 

I just wanted to follow up with a simple example to illustrate what Ken
is talking about here.  If I have the following directory structure:

  Top/
     Makefile.PL
     MANIFEST
     sub1/
         Makefile.PL
         sub2/
             Makefile.PL

and I execute `perl Makefile.PL`, then it magically recognizes that
there are Makefile.PL files in subdirectories and creates Makefiles for
those directories.  If I replace Makefile.PL with Build.PL, that magic
no longer appears to happen.  Additionally, `perl Build.PL` croaks
because there is no lib/ directory, and in the above scheme, there may
not always be a lib directory.  I've attached two tarballs with
Makefile.PLs and Build.PLs to illustrate.

Thanks,
Scott
