URI::Nested provides support for nested URIs, where the scheme is a prefix, and the remainder of the URI is another URI.

The Perl module Geo::IP looks up location and network information by IP Address.

This module provides functions to deal with IPv4/IPv6 addresses. The module can be used as a class, allowing the user to instantiate IP objects, which can be single IP addresses, prefixes, or ranges of addresses. There is also a procedural way of accessing most of the functions. Most subroutines can take either IPv4 or IPv6 addresses transparently.

Package extracted from SOAP::Lite. Slightly modified to work on multiple platforms.

This package provides a client library for Vipul's Razor. Vipul's Razor is a distributed, collaborative, spam detection and filtering network. Through user contribution, Razor establishes a distributed and constantly updating catalogue of spam in propagation that is consulted by email clients to filter out known spam. Detection is done with statistical and randomized signatures that efficiently spot mutating spam content. User input is validated through reputation assignments based on consensus on report and revoke assertions which in turn is used for computing confidence values associated with individual signatures.

This package provides a HTML and XML DOM parser. It also supports CSS selectors.

This module defines a format for database URIs, and provides a URI class to handle these.

Apache SpamAssassin is an anti-spam platform giving system administrators a filter to classify email and block spam (unsolicited bulk email). It uses a robust scoring framework and plug-ins to integrate a wide range of advanced heuristic and statistical analysis tests on email headers and body text including text analysis, Bayesian filtering, DNS blocklists, and collaborative filtering databases.

This package provides a class method constructs a new Net::IMAP::Simple object. It takes one required parameter which is the server to connect to, and additional optional parameters.

ExtUtils::Config is an abstraction around the %Config hash. By itself it is not a particularly interesting module by any measure, however it ties together a family of modern toolchain modules.

Class::Inspector allows you to get information about a loaded class.

This Perl module facilitates the creation and modification of PDF files.

List::SomeUtils::XS is a XS implementation for List::SomeUtils. There are no user-facing parts here. See List::SomeUtils for API details.

Text::TabularDisplay simplifies displaying textual data in a table. The output is identical to the columnar display of query results in the mysql text monitor.

Devel::LexAlias provides the ability to alias a lexical variable in a subroutines scope to one of your choosing.

The package provides Perl bindings to OpenGL, GLU and FreeGLUT.

This module provides a small, fast utility for working with file paths.

This module provides a facility for creating non-modifiable variables in Perl. This is useful for configuration files, headers, etc. It can also be useful as a development and debugging tool for catching updates to variables that should not be changed.

This package provides tools for inspecting subroutines in Perl.

Sys::Hostname::Long tries very hard to get the full hostname of a system.

A shared memory cache through an mmap'ed file. It's core is written in C for performance. It uses fcntl locking to ensure multiple processes can safely access the cache at the same time. It uses a basic LRU algorithm to keep the most used entries in the cache.

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

This module tries to make install path resolution as easy as possible.

This module facilitates using Moose or Mouse modules without changing the code. By default, Mouse will be provided to libraries, unless Moose is already loaded, or explicitly requested by the end-user. End users can force the decision of which backend to use by setting the environment variable ANY_MOOSE to be Moose or Mouse.
