AnyEvent is a Perl framework for event-based programming

AnyEvent(similar to POE and Twisted) is a framework for event-based programming. It comes with a number of different implementations while maintaining the same API(unless otherwise mentioned in the documentation). The current implementations are POE,Perl(pure Perl),IOAsync,EV,Event,EventLib,Cocoa,FLTK,Glib,Irssi,Qt,Tk.

It can be used for building high-performance applications that scale well. At the same time, synchronization primitives are available(condition variables), polling(via poll or epoll), running periodic tasks, inotify support(via AnyEvent::Filesys::Notify), database support(via AnyEvent::DBI), forking(via AnyEvent::Fork) and it comes with a built-in non-blocking HTTP client(AnyEvent::HTTP). There are many modules that extend AnyEvent's functionality which can be found on CPAN.
