This module lets you attempt to measure, from your operating system's perspective, how much memory a process is using at any given time.

A chained accessor is one that always returns the object when called with parameters (to set), and the value of the field when called with no arguments. This module subclasses Class::Accessor in order to provide the same mk_accessors interface.

The first priority of Set::Scalar is to be a convenient interface to sets (as in: unordered collections of Perl scalars). While not designed to be slow or big, neither has it been designed to be fast or compact.

This package contains functions to manipulate a MANIFEST file. The package exports no functions by default. The following are exported on request: mkmanifest, manifind, manicheck, filecheck, fullcheck, skipcheck, maniread, maniskip, manicopy, maniadd.

This module provides a simple syntax for creating object classes.

Text::BibTeX is a Perl library for reading, parsing, and processing BibTeX files. Text::BibTeX gives you access to the data at many different levels: you may work with BibTeX entries as simple field to string mappings, or get at the original form of the data as a list of simple values (strings, macros, or numbers) pasted together.

Carp::Assert is intended for a purpose like the ANSI C library assert.h.

This module tries to make it easy to build Perl extensions that use functions and typemaps provided by other perl extensions. This means that a perl extension is treated like a shared library that provides also a C and an XS interface besides the perl one.

DateTime::Format::Flexible attempts to take any string you give it and parse it into a DateTime object.

This module implements most of `strptime(3)`, the POSIX function that is the reverse of `strftime(3)`, for `DateTime`. While `strftime` takes a `DateTime` and a pattern and returns a string, `strptime` takes a string and a pattern and returns the `DateTime` object associated.

This is a Moose role which provides an alternate constructor for creating objects using parameters passed in from the command line.

This module implements the Perl foreign function interface XS for C++; it is a thin layer over plain XS.

This module allows you to execute code when perl finished compiling the surrounding scope.

Given a list of scalars or reference variables, Data::Dumper writes out their contents in Perl syntax. The references can also be objects. The content of each variable is output in a single Perl statement. It handles self-referential structures correctly.

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

These self-contained Perl modules provide cryptography based on the LibTomCrypt library.

Data::Perl is a container class for the following classes:

• Data::Perl::Collection::Hash

• Data::Perl::Collection::Array

• Data::Perl::String

• Data::Perl::Number

• Data::Perl::Counter

• Data::Perl::Bool

• Data::Perl::Code

The Readonly module is an effective way to create non-modifiable variables. However, it's relatively slow.

The reason it's slow is that is implements the read-only-ness of variables via tied objects. This mechanism is inherently slow. Perl simply has to do a lot of work under the hood to make tied variables work.

This module corrects the speed problem, at least with respect to scalar variables. When Readonly::XS is installed, Readonly uses it to access the internals of scalar variables. Instead of creating a scalar variable object and tying it, Readonly simply flips the SvREADONLY bit in the scalar's FLAGS structure.

Safe::Hole can execute outside defined subroutines in the original main compartment from the Safe compartment.

This module implements the Brew edit distance that is very close to the dynamic programming technique used for the Wagner-Fischer (and so for the Levenshtein) edit distance.

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.

Text::Patch combines source text with given diff (difference) data. Diff data is produced by Text::Diff module or by the standard diff utility.

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.

List::MoreUtils::XS provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.
