This is a great module, very easy to use and I like Moose and the way it leverages OOP to handle cross-platform issues. I am using it for several production systems and have been very happy with it. All hail the Autarch! (Had to get my Gene Wolfe shout out there).
Moose-infected garbage for monitoring changes to files. There are lots of better solutions on CPAN, including EV, Linux::Inotify2, and AnyEvent::Inotify::Simple.
