## File: pdlmaker.plm
## Author: Bryan Jurish <moocow@cpan.org>
## Description: hacks for CPAN-friendly PDL module distribution
##
## Usage:
## + optionally set the variable $MY::README (boolean); default is
## $MY::README = grep {-e $_} (<README.txt>,<README.pod>,<README.rpod>)
## + read this file in top-level Makefile.PL:
## require "pdlmaker.plm";
## + call pdlmaker_init([$pdfile, $pmbase, $module]) as for pdlpp_stdargs()
## - will actually call pdlpp_stdargs() and return that hash if called in list context
## + call WriteMakefile() as usual
## + omit the pdlpp_postamble() call from MY::postamble()
## (you still need to 'use PDL::Core::Dev' though)
##
## Effects:
## + clobbers sub ExtUtils::MakeMaker::WriteMakefile()
## - unlinks all @pdpm files before calling "real" WriteMakefile()
## + clobbers/appends MY::depend (appends)
## x- adds @pdpm dependencies to dist,distcheck,create_distdir
## - also adds README.txt dependencies if README.txt or README.rpod is present
## + clobbers/appends MY::special_targets (appends)
## - adds (pm|pod|rpod) -> (txt|html) rules
## + clobbers/appends MY::postamble (appends)
## - adds pdlpp_postamble($package) if $package is specified
