Other than the fact that, IIRC, pmtools wouldn't install for me on Windows. (I should lay down a bug number for it.)
pmtools provides this and many other. The best would for the author be to remove this module from CPAN altogether or if it doesn anything that pmtools doesn't see that it get integrated in pmtools.
I changed the rating from one star to undef as it seems that some people can't get pmtools to work on Windows. My opinion hasn't changed though.
