=head1 NAME
ExtUtils::MM - OS adjusted ExtUtils::MakeMaker subclass
=head1 SYNOPSIS
require ExtUtils::MM;
my $mm = MM->new(...);
=head1 DESCRIPTION
B<FOR INTERNAL USE ONLY>
ExtUtils::MM is a subclass of ExtUtils::MakeMaker which automatically
chooses the appropriate OS specific subclass for you
(ie. ExtUils::MM_Unix, etc...).
It also provides a convenient alias via the MM class (I didn't want
MakeMaker modules outside of ExtUtils/).
This class might turn out to be a temporary solution, but MM won't go
away.
