Excerpt: The Perl Object Environment or POE is a library of Perl modules written in the Perl programming language by Rocco Caputo et al. From CPAN: "POE originally was developed as the core of a persistent object server and runtime environment. It has evolved into a general purpose multitasking and networking framework, encompassing and providing a consistent interface to other event loops such as Event and the Tk and Gtk toolkits." POE, The Perl Object Environment can be thought of as a tiny modular operating system. One or more POE programs or instances can be run concurrently and are generally well suited for cooperative multitasking. The POE package consists of namespaces and abstractions that guide future development of POE in an open-ended CPAN-style convention. The informal architecture consists of a set of layers with a kernel on the bottom. This tiny kernel represents the events layer which operates as the main loop of each running POE instance. The first call is to the "event dispatcher" - POE::Kernel. The POE::Kernel namespace contains a suite of functions which are plugged-in to the kernel itself. These loop abstractions are designed after POE's standardized event loop bridge interface - POE::Loop. These can be mixed and matched as needed to provide runtime services and a lean facility for interprocess communication. The basic functions are POE::Loop::Event, POE::Loop::Poll and POE::Loop::Select. Also available are POE::Loop::Tk and POE::Loop::Gtk that offer hooks into other loop bridges in the external environment. If that is...More: http://booksllc.net/?id=22194
