portable multitasking and networking framework for perl
POE is a framework for cooperative, event driven multitasking and networking in Perl. Other languages have similar frameworks. Python has Twisted. TCL has "the event loop". POE provides a unified interface for several other event loops, including select(), IO::Poll, Glib, Gtk, Tk, Wx, and Gtk2. Many of these event loop interfaces were written by others, with the help of POE::Test::Loops. They may be found on the CPAN.
