CGI::Application is a Perl framework intended to make it easier to create sophisticated, reusable Web-based applications. This module implements a methodology which can make Web software easier to design, easier to document, easier to write, and easier to evolve. CGI::Application builds on standard, non-proprietary technologies and techniques, such as the Common Gateway Interface and Lincoln D. Stein's excellent CGI.pm module. CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system, or Web server.
libpubsub provides everything needed to set up a simple publish/subscribe environment. It allows a programmer to let several processes (not necessarily on the same host) exchange information with each other in a very easy way. It is mainly intended for use in C++ applications, but the package also includes a tool to let shell scripts use pubsub.
