Statistics::Distribution::Generator A means of composing random number generators together using simple operators Install using the CPAN interface of your choice, or download from CPAN, and then perl Makefile.PL make make install If you want to risk random breakage (this is a random number generator after all), you may run "make test" before "make install". The test suite is imperfect, however, precisely because it's hard to predict what random numbers will do, so you may run into test "failures" that are merely the result of something very unlikely happening, rather than something being broken.
