DocPerl provides a Web-based interface to Perl's Plain Old Documentation (POD). It is a graphical, easy-to-use interface to POD, automatically listing all installed modules on the local host, and any other nominated directories containing Perl files. DocPerl can also display a summary of the APIs defined by files and the code of those files. It can search the POD documentation for module names and for functions defined in modules.
CGI::Application::Generator provides a means by which a CGI::Application-based module can be created from code, as opposed to being written by hand. This module is intended to create the shell of an application module, based on the specification you provide. It will not output a completely functional application without additional coding. It will, however, create the structural parts of your application common to all CGI::Application-based modules. This module is intended to ease the creation of new CGI::Application modules and to encourage standardization of CGI::Application coding styles.
WebTools is "system" of multiple modules and libraries. Along with template engine capabilities, it features session management, global variables support, cookies support, and various database interfaces. It also features a pure Perl mail client, categories management, form checking, and libraries such as a CGI-based downloading library, HTML parsers, and a library that makes PHP functions available to Perl for ease of development.
Pod::Manual is a module that gathers the pod of several Perl modules into a comprehensive manual. Its primary objective is to generate a document that can be printed, but it also allow to output the document into other formats (e.g., docbook). podmanual is a utility that uses Pod::Manual.
