This Perl module provides Chinese encodings that are not part of Perl by default, including "BIG5-1984", "BIG5-2003", "BIG5PLUS", "BIG5EXT", "CCCII", "EUC-TW", "CNS11643-*", "GB18030", and "UNISYS".

Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for names with the same pronunciation to be encoded to the same representation so that they can be matched despite minor differences in spelling.

This module implements the original soundex algorithm developed by Robert Russell and Margaret Odell, patented in 1918 and 1922, as well as a variation called "American Soundex" used for US census data, and current maintained by the National Archives and Records Administration (NARA).

This package eases the writing of command line utilities, accepting commands and subcommands and so on. These commands can form a tree, which is mirrored in the package structure. On invocation, each command along the path through the tree (starting from the top-level command through to the most specific one) is instantiated.

Text::CSV provides facilities for the composition and decomposition of comma-separated values. An instance of the Text::CSV class can combine fields into a CSV string and parse a CSV string into fields.

This module understands the formats used by MySQL for its DATE, DATETIME, TIME, and TIMESTAMP data types. It can be used to parse these formats in order to create DateTime objects, and it can take a DateTime object and produce a string representing it in the MySQL format.

Pod::Parser is a base class for creating POD filters and translators. It handles most of the effort involved with parsing the POD sections from an input stream, leaving subclasses free to be concerned only with performing the actual translation of text.

NOTE: This module is considered legacy. New projects should prefer Pod::Simple instead.

The File::LibMagic module is a simple perl interface to libmagic from the file package.

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.

Conf::Libconfig is a Perl interface to the libconfig configuration file library. It support scalar, array, and hash data structures just like its C/C++ counterpart. It reduces the effort required to implement a configuration file parser in your Perl programme and allows sharing configuration files between languages.

With this module, you can calculate terminal character widths that vary by locale. This module supplies features similar to wcwidth(3) and wcswidth(3) in C language.

The DateTime::Set module provides a date/time sets implementation. It allows, for example, the generation of groups of dates, like "every wednesday", and then find all the dates matching that pattern, within a time range.

Class::Data::Inheritable is for creating accessor/mutators to class data. That is, if you want to store something about your class as a whole (instead of about a single object). This data is then inherited by your subclasses and can be overridden.

This package provides the docmake command-line tool, and the App::XML::DocBook::Docmake and App::XML::DocBook::Builder Perl modules.

It translates DocBook/XML mark-up into various other documentation formats such as XHTML, RTF, PDF, and XSL-FO, using the more low-level tools. It aims to be a replacement for xmlto.

Pegex is an Acmeist parser framework. It allows you to easily create parsers that will work equivalently in lots of programming languages. The inspiration for Pegex comes from the parsing engine upon which the postmodern programming language Perl 6 is based on. Pegex brings this beauty to the other justmodern languages that have a normal regular expression engine available.

This module overrides CORE::GLOBAL::require with a code reference in a way that plays nice with any existing overloading and ensures the right calling package is in scope.

Chaolin Zhang's Perl Library (czplib) contains assorted functions and data structures for processing and analysing genomic and bioinformatics data.

MIME::Base64 module provides functions to encode and decode strings into and from the base64 encoding specified in RFC 2045 - MIME (Multipurpose Internet Mail Extensions). The base64 encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. A 65-character subset ([A-Za-z0-9+/=]) of US-ASCII is used, enabling 6 bits to be represented per printable character.

Data::Uniqid provides three simple routines for generating unique ids. These ids are coded with a Base62 system to make them short and handy (e.g. to use it as part of a URL).

Config::INI::Reader::Ordered is a Perl library for parsing .ini files that returns the sections in order.

This module converts Perl data structures to JSON and vice versa.

Template::Timer provides inline profiling of the template processing in Perl code.

Data::Tumbler - Dynamic generation of nested combinations of variants.

File::Find::Rule is a friendlier interface to File::Find. It allows you to build rules which specify the desired files and directories.

CPAN::DistnameInfo uses heuristics to extract the distribution name and version from filenames.
