MooseX::NonMoose allows for easily subclassing non-Moose classes with Moose, taking care of the details connected with doing this, such as setting up proper inheritance from Moose::Object and installing (and inlining, at make_immutable time) a constructor that makes sure things like BUILD methods are called. It tries to be as non-intrusive as possible.

This module lets you attempt to measure, from your operating system's perspective, how much memory a process is using at any given time.

This module provides convenience methods that let you easily create DateTime::Set objects for RFC 2445 style recurrences.

The package provides a number of useful typemaps as submodules of ExtUtils::Typemaps.

Date::Manip is a series of modules for common date/time operations, such as comparing two times, determining a date a given amount of time from another, or parsing international times.

This module, ReadKey, provides ioctl control for terminals so the input modes can be changed (thus allowing reads of a single character at a time), and also provides non-blocking reads of stdin, as well as several other terminal related features, including retrieval/modification of the screen size, and retrieval/modification of the control characters.

This package provides basic statistics functions like median(), mean(), variance() and stddev().

A shared memory cache through an mmap'ed file. It's core is written in C for performance. It uses fcntl locking to ensure multiple processes can safely access the cache at the same time. It uses a basic LRU algorithm to keep the most used entries in the cache.

This module facilitates using Moose or Mouse modules without changing the code. By default, Mouse will be provided to libraries, unless Moose is already loaded, or explicitly requested by the end-user. End users can force the decision of which backend to use by setting the environment variable ANY_MOOSE to be Moose or Mouse.

The Digest::SHA Perl module implements the hash functions of the SHA family. It also provides the shasum binary.

This package contains a selection of subroutines that people have expressed would be nice to have in the perl core, but the usage would not really be high enough to warrant the use of a keyword, and the size so small such that being individual extensions would be wasteful.

The functions exported by this module deal with runtime handling of Perl modules, which are normally handled at compile time.

This module provides three utility subroutines that make it easier to develop interactive applications: is_interactive(), interactive(), and busy().

Some Perl modules need to ship C libraries together with their Perl code. Although there are mechanisms to compile and link (or glue) C code in your Perl programs, there isn't a clear method to compile standard, self-contained C libraries. This module main goal is to help in that task.

This module allows you to execute code when perl finished compiling the surrounding scope.

Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.

Data::OptList provides a simple syntax for name/value option pairs.

Sys::Syscall allows one to use epoll and sendfile system calls from Perl. Support is mostly Linux-only for now, but other syscalls/OSes are planned for the future.

ExtUtils::Config is an abstraction around the %Config hash. By itself it is not a particularly interesting module by any measure, however it ties together a family of modern toolchain modules.

Crypt::CBC is a Perl-only implementation of the cryptographic Cipher Block Chaining (CBC) mode. In combination with a block cipher such as Crypt::Rijndael you can encrypt and decrypt messages of arbitrarily long length. The encrypted messages are compatible with the encryption format used by SSLeay.

This module provides tools to deal with International Standard Music Numbers.

Crypt::MySQL emulates the MySQL PASSWORD() function. The module does not depend on an interface to the MySQL database server. This enables the comparison of encrypted passwords without the need for a real MySQL environment.

This package provides some compilation helpers so you can link Fortran libraries into C libraries.

This module lets you require other modules where the module name is in a variable, something you can't do with the require built-in.
