ExtUtils::MM - OS adjusted ExtUtils::MakeMaker subclass
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.
