Finance::CompanyNames is a Perl module for finding names of companies in arbitrary English text. The module can locate names and their variants, using statistical language processing methods. It is possible to automatically locate instances of "XYZ Corp" as well as "XYZ Corp.", "XYZ Corporation", and even "XYZ". This module fulfills a common need for programmers in the financial and investment communities.
find_used_modules looks over your entire system and figures out which modules people are using. It then builds a Perl script that can be used to test to make sure that all those modules are available. The purpose of all this is to allow Perl to be upgraded without breaking too many installed Perl programs.
CGI.pm uses objects to create Web fill-out forms on the fly and to parse their contents. Instead of remembering the syntax for HTML form elements, developers can just make a series of Perl function calls. An important fringe benefit of this is that the value of the previous query is used to initialize the form, so that the state of the form is preserved from invocation to invocation.
The CentralNic Toolkit is CentralNic's system for instantaneous Registry-Registrar Communications. Registrars can use this system to register and modify CentralNic domain names in real time, with no delays for human intervention or e-mail processing. The Toolkit also provides advanced and efficient methods for searching for and querying domain names and whois records, and retrieving account information.
Zoidberg (a.k.a. zoid) provides a modular Perl shell written, configured, and operated entirely in Perl. It aspires to be a fully operational login shell with all the features one normally expects. But it also gives direct access to Perl objects and data structures from the command line, and allows you to run Perl code within the scope of your command line.
PerlQt-3 is a full-fledged object oriented interface to Trolltech's Qt GUI toolkit version 3.x, for Perl >= 5.6.0 on POSIX systems.
