=head1 NAME
makesimple - De-sugar GNU makefiles to its simplest form using the GmakeDB parser
=head1 SYNOPSIS
$ makesimple -f myGNUmakefile.mk > simplest.mk
=head1 DESCRIPTION
The makesimple script is a makefile simplifier. It
converts a full-fledged GNU makefile to a highly de-sugared basic
makefile which is almost a call-path tree dump.
=head1 SVN REPOSITORY
For the very latest version of this script, check out the source from
L<http://github.com/agentzh/makefile-parser-pm>.
There is anonymous access to all.
