=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.
