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

Pod::Simple is a Perl library for parsing text in the Pod (plain old documentation) markup language that is typically used for writing documentation for Perl and for Perl modules.

This package is a plugin to tidyall allowing integration with the Test::Count module, to keep track of the number of tests in a test file.

This module implements Spreadsheet::XLSX parsing Microsoft Excel 2007 xlsx files.

This module compares arbitrary data structures to see if they are copies of each other.

PAR::Dist is a toolkit to create and manipulate PAR distributions.

This package provides asynchronous and advanced input/output for Perl.

Params::Util provides a basic set of importable functions that makes checking parameters easier.

It's boring to deal with opening files for IO, converting strings to handle-like objects, and all that. With Mixin::Linewise::Readers and Mixin::Linewise::Writers, you can just write a method to handle handles, and methods for handling strings and file names are added for you.

Role::Tiny is a minimalist role composition tool.

This module allows libraries to have a dependency to a small module instead of the full Log-Report distribution. The full power of Log::Report is only released when the main program uses that module. In that case, the module using the Optional will also use the full Log::Report, otherwise the dressed-down Log::Report::Minimal version.

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 package is a companion module to DateTime.pm. It implements the Julian calendar. It supports everything that DateTime.pm supports and more: about one day per century more, to be precise.

B::Keywords supplies several arrays of exportable keywords: @Scalars, @Arrays, @Hashes, @Filehandles, @Symbols, @Functions, @Barewords, @TieIOMethods, @UNIVERSALMethods and @ExporterSymbols.

This package allows you to stop processing the entire test suite after the first failure, instead of going all the way through it.

Parallel::ForkManager is intended for use in operations that can be done in parallel where the number of processes to be forked off should be limited.

This module allows you to specify those constants that should be documented in your POD, and pull them out a run time in a fairly arbitrary fashion.

Pod::Constants uses Pod::Parser to do the parsing of the source file. It has to open the source file it is called from, and does so directly either by lookup in %INC or by assuming it is $0 if the caller is main (or it can't find %INCcaller()).

Socket::MsgHdr provides advanced socket messaging operations via sendmsg and recvmsg.

It also allows manipulating ancillary data or so-called control information (cmsghdr). This ancillary data may be used for file descriptor passing, IPv6 operations, and a host of implementation-specific extensions.

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

The mix_class function provided by this module dynamically generates anonymous classes with specified inheritance. This is useful where an incomplete class requires use of a mixin in order to become instantiable.

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.

This module provides some extra datatypes that are used by common serialisation formats such as JSON or CBOR.

Module::Find lets you find and use modules in categories. This can be useful for auto-detecting driver or plugin modules. You can differentiate between looking in the category itself or in all subcategories.

This Perl module provides Unicode normalization forms.
