Class::Method::Modifiers provides three modifiers: before, around, and after. before and after are run just before and after the method they modify, but can not really affect that original method. around is run in place of the original method, with a hook to easily call that original method.

PPIx::Utils is a collection of utility functions for working with PPI documents. The functions are organized into submodules, and may be imported from the appropriate submodules or via this module.

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

This module provides configure time utilities for using C headers, libraries, or OS features.

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

The Digest::CRC module calculates CRC sums of all sorts. It contains wrapper functions with the correct parameters for CRC-CCITT, CRC-16 and CRC-32.

This package enables you to do generic message logging throughout programs and projects. Every message will be logged with stacktraces, timestamps and so on. You can use built-in handlers immediately, or after the fact when you inspect the error stack. It is highly configurable and lets you even provide your own handlers for dealing with messages.

Like Tcl's uplevel() function, but not quite so dangerous. The idea is just to fool caller(). All the really naughty bits of Tcl's uplevel() are avoided.

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

This module provides a simple but extensible way of having plugins for your Perl module.

Devel::GlobalDestruction provides a function returning the equivalent of "${^GLOBAL_PHASE} eq 'DESTRUCT'" for older perls.

This module implements an interface to the Linux 2.6.13 and later Inotify file change notification system.

Strictures turns on strict and make all warnings fatal when run from within a source-controlled directory.

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.

Sys::CPU is a module for counting the number of CPUs on a system, and determining their type and clock speed.

This module provides various portable helper functions for module building modules.

This package provides Digest::SHA1, an implementation of the NIST SHA-1 message digest algorithm for use by Perl programs.

This module provides $CWD and @CWD as alternatives to chdir().

Many Perl distributions use a Build.PL file instead of a Makefile.PL file to drive distribution configuration, build, test and installation. Traditionally, Build.PL uses Module::Build as the underlying build system. This module provides a simple, lightweight, drop-in replacement. Whereas Module::Build has over 6,700 lines of code; this module has less than 120, yet supports the features needed by most distributions.

This module allows you to build a variable package that contains a package template and can use it to build variant packages at runtime. Your variable package will export a subroutine which will build a variant package, combining its arguments with the template, and return the name of the new variant package. The implementation does not care about what kind of packages it builds, be they simple function exporters, classes, singletons or something else.

Collection of classes that wrap fundamental data types that exist in Perl. These classes and methods as they exist today are an attempt to mirror functionality provided by Moose's Native Traits. One important thing to note is all classes currently do no validation on constructor input.

Storable brings persistence to your Perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time.

Text::Aligner exports a single function, align(), which is used to justify strings to various alignment styles.

This module provides an interface to layout and image generation of directed and undirected graphs in a variety of formats (PostScript, PNG, etc.) using the dot, neato, twopi, circo, and fdp programs from the Graphviz project. This package is deprecated in favour of GraphViz2.
