The package contains the ExtUtils::ParseXS module to convert Perl XS code into C code, the ExtUtils::Typemaps module to handle Perl/XS typemap files, and their submodules.

Loading MooX::StrictConstructor makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it dies.

Set::IntSpan manages sets of integers. It is optimized for sets that have long runs of consecutive integers.

Set::Infinite is a set theory module for infinite sets.

A String::Util module of small, handy functions for processing strings in various ways.

Getopt::Long::Descriptive is yet another Getopt library. It's built atop Getopt::Long, and gets a lot of its features, but tries to avoid making you think about its huge array of options. It also provides usage (help) messages, data validation, and a few other useful features.

Crypt::UnixCrypt_XS implements the DES-based Unix crypt function. For those who need to construct non-standard variants of crypt, the various building blocks used in crypt are also supplied separately.

Alien::SDL can be used to detect and get configuration settings from an installed SDL and related libraries. Based on your platform it offers the possibility to download and install prebuilt binaries or to build SDL & co.: from source codes.

The Lingua::EN::Sentence module contains the function get_sentences, which splits text into its constituent sentences, based on a regular expression and a list of abbreviations (built in and given).

This is a module for computing the difference between two files, two strings, or any other two lists of things. It uses an intelligent algorithm similar to (or identical to) the one used by the Unix "diff" program. It is guaranteed to find the *smallest possible* set of differences.

Routines to manipulate defhash, a convention to define things more precisely and uniformly using a hash, in Perl.

Crypt::PasswdMD5 provides various crypt()-compatible interfaces to the MD5-based crypt() function found in various *nixes. It is based on the implementation found on FreeBSD 2.2.[56]-RELEASE.

This module can serve as a transparent interface to any TIEHASH package that is required to store arbitrary perl data, including nested references. Thus, this module can be used for storing references and other arbitrary data within DBM databases.

This Digest::Perl::MD5 has the same interface as the much faster Digest::MD5, but it's a pure Perl implementation of MD5. Because of this it is slow but it works without C code.

Switch is a Perl module which implements a generalized case mechanism. The module augments the standard Perl syntax with two new statements: switch and case.

The Text::Balanced module can be used to extract delimited text sequences from strings.

This module allows you to speed up your sleep(), alarm(), and time() calls.

This package provides tools for sorting and comparing Unicode data.

This is a meta-package containing specifications for installing all the Test::Run plugins.

This is yet another implementation of Term::Size. Now in pure Perl, with the exception of a C probe run at build time.

This package provides the IO::Pty and IO::Tty Perl interfaces to pseudo ttys.

This package provides real threads for Perl.

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

This policy checks for perlsecret operators in your code and warns you about them. You can override the secrets that are allowed or disallowed using the parameters allow_secrets and disallow_secrets. The default is to simply disallow everything.
