Module::Install is a package for writing installers for CPAN (or CPAN-like) distributions that are clean, simple, minimalist, act in a strictly correct manner with ExtUtils::MakeMaker, and will run on any Perl installation version 5.005 or newer.

File::Remove::remove removes files and directories. It acts like /bin/rm, for the most part. Although unlink can be given a list of files, it will not remove directories; this module remedies that. It also accepts wildcards, * and ?, as arguments for file names.

Eksblowfish is a variant of the Blowfish cipher, modified to make the key setup very expensive. This doesn't make it significantly cryptographically stronger but is intended to hinder brute-force attacks. Eksblowfish is a parameterised (family-keyed) cipher. It takes a cost parameter that controls how expensive the key scheduling is. It also takes a family key, known as the "salt". Cost and salt parameters together define a cipher family. Within each family, the key determines the encryption function. This distribution also includes an implementation of bcrypt, the Unix crypt() password hashing algorithm based on Eksblowfish.

Path::Iterator::Rule iterates over files and directories to identify ones matching a user-defined set of rules. The API is based heavily on File::Find::Rule, but with more explicit distinction between matching rules and options that influence how directories are searched. A Path::Iterator::Rule object is a collection of rules (match criteria) with methods to add additional criteria. Options that control directory traversal are given as arguments to the method that generates an iterator.

A summary of features for comparison to other file finding modules:

• provides many helper methods for specifying rules

• offers (lazy) iterator and flattened list interfaces

• custom rules implemented with callbacks

• breadth-first (default) or pre- or post-order depth-first searching

• follows symlinks (by default, but can be disabled)

• directories visited only once (no infinite loop; can be disabled)

• doesn't chdir during operation

• provides an API for extensions

As a convenience, the PIR module is an empty subclass of this one that is less arduous to type for one-liners.

Set::Object provides efficient sets, unordered collections of Perl objects without duplicates for scalars and references.

This Perl module provides various functions to quickly sort arrays by one or multiple calculated keys.

Devel::CheckCompiler is a tiny module to check whether a compiler is available. It can test for a C99 compiler, or you can tell it to compile a C source file with optional linker flags.

While Mouse attributes provide a way to name your accessors, readers, writers, clearers and predicates, MouseX::NativeTraits provides commonly used attribute helper methods for more specific types of data.

YAML::Syck provides a Perl interface to the libsyck data serialization library. It exports the Dump and Load functions for converting Perl data structures to YAML strings, and the other way around.

Hash::Merge merges two arbitrarily deep hashes into a single hash. That is, at any level, it will add non-conflicting key-value pairs from one hash to the other, and follows a set of specific rules when there are key value conflicts. The hash is followed recursively, so that deeply nested hashes that are at the same level will be merged when the parent hashes are merged.

This way of associating structs with Perl space objects is designed to supersede Perl's builtin T_PTROBJ with something that is extensible (structs can be associated with any data type) and opaque (the C pointer is neither visible nor modifiable from Perl space).

RFCs 2822 and 822 specify date formats to be used by email. This module parses and emits such dates.

Array::Utils is a small pure-perl module containing list manipulation routines.

XSLoader module defines a standard simplified interface to the dynamic linking mechanisms available on many platforms. Its primary purpose is to implement cheap automatic dynamic loading of Perl modules.

Mozilla::CA provides a copy of Mozilla's bundle of Certificate Authority certificates in a form that can be consumed by modules and libraries based on OpenSSL.

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

Sub::Quote provides an efficient generation of subroutines via string eval.

YAML::Tiny is a perl class for reading and writing YAML-style files, written with as little code as possible, reducing load time and memory overhead.

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

Config::Tiny is a Perl class to read and write .ini style configuration files with as little code as possible, reducing load time and memory overhead.

This module is primarily for reading human written files, and anything we write shouldn't need to have documentation/comments. If you need something with more power move up to Config::Simple, Config::General or one of the many other Config::* modules.

Unicode::LineBreak implements the line breaking algorithm described in Unicode Standard Annex #14. The East_Asian_Width property defined by Annex #11 is used to determine breaking positions.

This package provides a package to change terminal modes and perform non-blocking reads.

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.

Devel::CheckLib is a Perl module that checks whether a particular C library and its headers are available. You can also check for the presence of particular functions in a library, or even that those functions return particular results.
