qpsmtpd is a flexible smtpd daemon written in Perl. Apart from the core SMTP features, all functionality is implemented in small "extension plugins" using the easy-to-use object oriented plugin API. qpsmtpd was originally written as a drop-in qmail-smtpd replacement, but now it also includes an smtp forward and a postfix "backend".

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.
