IO::Null ======== Calling a constructor of this class always succeeds, returning a new null filehandle. Writing to any object of this class is always a no- operation, and returns true. Reading from any object of this class is always nooperation, and returns empty-string or empty-list, as appropriate.

IO::All - IO::All combines all of the best Perl IO modules IO::All combines all of the best Perl IO modules into a single Spiffy object oriented interface to greatly simplify your everyday Perl IO idioms. It exports a single function called io, which returns a new IO::All object. And that object can do it all!

IO::Prompter exports a single subroutine, prompt, that prints a prompt (but only if the program's selected input and output streams are connected to a terminal), then reads some input, then chomps it, and finally returns an object representing that text.

This module provides a simple API for publishing messages to channels and for subscribing to them. When a message is published on a channel, all subscribers currently in that channel will get it on their next "get" or "get_all" call. Currently, it offers three backends: "DBM_Deep" for on-disk storage, "Memcached" for possibly multi-host storage, and "PlainHash" for single-process storage.

Log::Dispatch::FileShared is an output class for logging to shared files under the Log::Dispatch system. Log messages are written using the flock file locking mechanism on a per write basis which means that this module is suitable for sharing a log file in a multitasking environment.

Module::Versions handles versions of loaded modules with a flexible result interface. The main goal is to get as much version informations as possible about a module or module list with a simple call interface and an absolutely flexible result interface. Module::Versions handles *loaded* and *loadable* modules.

POE::Component::JobQueue manages a finite pool of worker sessions as they handle an arbitrarily large number of tasks. It often is used as a form of flow control, preventing a large group of tasks from exhausting some sort of resource.

POE is a general purpose multitasking and networking framework. POE does standard event loop things, cooperative multitasking, network clients and servers; includes a high level class library that takes care of event driven I/O; provides a framework for portable program components.

The Comprehensive Perl Archive Network (CPAN) is a very useful collection of Perl code. It has several indices of the files that it hosts, including a file named "02packages.details.txt.gz" in the "modules" directory. This file contains lots of useful information and this module provides a simple interface to the data contained within.

The Penguin module provides a framework within which a user on one host electronically signs a piece of Perl code, sends it to another host where the signature is checked and the code is executed with privileges that are particular to that user.
