[Module::Build] M::B subclass .pm file locations

[Ray Z. <rz...@co...>]

I'm looking for recommendations for how where to put my Module::Build  
sub-classes and how to set up @INC to find them.

Here's my scenario ... I'm working with a set of Perl packages that  
are organized as a base package A with a number of add-on packages.  
Let's call one of the add-on packages B. So A is a prerequisite for B  
(i.e. A must be installed in order to build, test and install any of  
B). I have a common Module::Build sub-class, call it Bbuilder, that I  
use for all B. Since A must be installed in order to build B anyway,  
it seems logical to have Bbuilder.pm be included as part of A. To  
build A, I have another M::B sub-class, call it Abuilder, which is a  
sub-class of Bbuilder.

If Bbuilder.pm is placed in A/lib, it gets installed as part of A and  
the Build.PL script for B is very straightforward. The question is,  
where do I put Abuilder.pm, and  how do I manipulate @INC inside the  
Build.PL script for A to get what I want. Are there conventions for  
where to put these things?

I'm currently thinking of putting Abuilder.pm in A/t and Bbuilder in  
A/lib and doing ...

	use lib qw( lib t );
	require Abuilder;

... at the beginning of Build.PL. Any better ideas?
