=head1 NAME
Bio::Root::Build - A common Module::Build subclass base for BioPerl distributions
=head1 SYNOPSIS
...TO BE ADDED
=head1 DESCRIPTION
This is a subclass of Module::Build so we can override certain methods and do
fancy stuff
It was first written against Module::Build::Base v0.2805. Many of the methods
here are copy/pasted from there in their entirety just to change one or two
minor things, since for the most part Module::Build::Base code is hard to
cleanly override.
B<Note>: per bug 3196, the majority of the code in this module has been revised
or commented out to bring it in line with the Module::Build API. In particular,
'requires/recommends' tags in the Build.PL file were not of the same format as
those for Module::Build, and so caused serious issues with newer versions
(including giving incorrect meta data). Other problematic methods involving
automatic installation of prereq modules via CPAN were also removed as they do
not work with more modern perl tools such as perlbrew and cpanm.
=head1 FEEDBACK
=head2 Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to
the Bioperl mailing list. Your participation is much appreciated.

http://bioperl.org/wiki/Mailing_lists - About the mailing lists
=head2 Support
Please direct usage questions or support issues to the mailing list:
I<bioperl-l@bioperl.org>
rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly
address it. Please include a thorough description of the problem
with code and data examples if at all possible.
=head2 Reporting Bugs
Report bugs to the Bioperl bug tracking system to help us keep track
of the bugs and their resolution. Bug reports can be submitted via
the web:
