Autodia is a command line Perl application that generates UML class diagrams from source code, SQL, and database connections.

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.
