File::ShareDir::Dist finds share directories for distributions. It is a companion module to File::ShareDir.

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

DateTime::Format::ISO8601 is a DateTime extension that parses almost all ISO8601 date and time formats.

Meta::Builder is designed to be a generic tool for writing Meta objects. Unlike specialized tools, Meta::Builder makes no assumptions about what metrics you will care about. Meta::Builder also makes it simple for others to extend your meta-object based tools by providing hooks for other packages to add metrics to your meta object.

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.

This module exposes interpreter threads to the Perl level.

Sub::Exporter is an incredibly powerful module, but with that power comes great responsibility, as well as some runtime penalties. This module is a "Sub::Exporter" wrapper that will let your users just use Exporter if all they are doing is picking exports, but use "Sub::Exporter" if your users try to use "Sub::Exporter"'s more advanced features, like renaming exports, if they try to use them.

Text::NeatTemplate provides a simple, middleweight but fast template engine, for when you need speed rather than complex features, yet need more features than simple variable substitution.

This module understands the formats used by SQLite for its date, datetime and time functions. It can be used to parse these formats in order to create DateTime objects, and it can take a DateTime object and produce a timestring accepted by SQLite.

This package provides a Perl library to read multiple hunks of data out of your DATA section.

Math::Round provides functions to round numbers, both positive and negative, in various ways.

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

Devel::OverloadInfo returns information about overloaded operators for a given class (or object), including where in the inheritance hierarchy the overloads are declared and where the code implementing it is.

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

This package provides encodings for JIS X 0212, which is also known as JIS 2000.

This module implements an expiry policy for Memoize that follows LRU semantics, that is, the last n results, where n is specified as the argument to the CACHESIZE parameter, will be cached.

This module provides various type-testing functions. These are intended for functions that care what type of data they are operating on. There are two flavours of function. Functions of the first flavour provide type classification only. Functions of the second flavour also check that an argument is of an expected type. The type enforcement functions handle only the simplest requirements for arguments of the types handled by the classification functions. Enforcement of more complex types may be built using the classification functions, or it may be more convenient to use a module designed for the more complex job, such as Params::Validate

The "mro" namespace provides several utilities for dealing with method resolution order and method caching in general in Perl 5.9.5 and higher. This module provides those interfaces for earlier versions of Perl (back to 5.6.0).

This module reads a file backwards line by line. It is simple to use, memory efficient and fast. It supports both an object and a tied handle interface.

It is intended for processing log and other similar text files which typically have their newest entries appended to them. By default files are assumed to be plain text and have a line ending appropriate to the OS. But you can set the input record separator string on a per file basis.

This package provides an efficient mechanism to look up ranges in Interval Trees.

This module provides a file handle that hides the beginning of a file, by modifying the seek() and tell() calls.

Data::Float is about the native floating point numerical data type. A floating point number is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native floating point type, classification functions and functions to manipulate floating point values at a low level.

Carp::Assert::More is a set of handy assertion functions for Perl.

Text::Haml implements Haml http://haml.info/docs/yardoc/file.REFERENCE.html specification.
