Back in the early days of the web, many people learned Perl because of a wonderful Perl library called CGI. It was simple enough to get started without knowing much about the language and powerful enough to keep you going, learning by doing was much fun. While most of the techniques used are outdated now, the idea behind it is not. Mojolicious is a new endeavor to implement this idea using modern technologies.

SOAP::Lite is a collection of Perl modules that provide a simple and lightweight interface to the SOAP, both on client and server side.

WWW::Pastebin::PastebinCom::Create provides functionality to paste on Pastebin without API keys.

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.

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

This package provides an old GeoIP database in the legacy .dat format. The data was collected before MaxMind changed the license and format of their databases. It is intended only as a compatibility package for SpamAssassin.

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

This module looks up the Gravatar for any email address by constructing a URL to get the image from gravatar.com. A Gravatar is a Globally Recognized Avatar for a given email address. This allows you to have a global picture associated with your email address.

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

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.

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

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 module is used by Schmorp's modules during configuration stage to test the installed perl for compatibility with his modules.

This module understands the W3CDTF date/time format, an ISO 8601 profile, defined at https://www.w3.org/TR/NOTE-datetime. This format is the native date format of RSS 1.0. It can be used to parse these formats in order to create the appropriate objects.

This module is a simple interface to extensible logging. It exists to abstract your logging interface so that logging is as painless as possible, while still allowing you to switch from one logger to another.

Exception::Class allows you to declare exception hierarchies in your modules in a "Java-esque" manner.

This module provides user-defined Unicode properties that deal with width status of East Asian characters, as specified in Unicode® Standard Annex #11.

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 subclass of Module::Build adds some tools and processes to make it easier to use for wrapping C++ using XS++ (ExtUtils::XSpp).

This module provide a convenient way to create directories of arbitrary depth and to delete an entire directory subtree from the file system.

Data::Dumper::Concise provides a dumper with Less indentation and newlines plus sub deparsing.

This package is a companion module to DateTime.pm. It implements the Julian calendar. It supports everything that DateTime.pm supports and more: about one day per century more, to be precise.

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.
