Text::Template is a module for doing dynamic content generation in Perl. You can embed any Perl code into a file, and then make a call to the module to `fill in' the blanks in the file. This is good for generating HTML pages and form letters. It was first released in 1995 and is very stable, very fast, and very reliable. It is also integrated with Perl's Safe module in case you don't trust the template author.
Beautifier (previously known as PSH, the PHP Syntax Highlighter) highlights and indents source code using highlight configuration files which are similar to Ultraedit highlighting files. It supports C, C#, Java, Perl, PHP, Pascal, Lisp, Mumps, Eiffel, Euphoria, and x86 Assembler, amongst others. It handles line/block comments, keyword highlighting, correct indentation, string highlighting, language contexts (allowing embedded languages), and selection highlighting. It is available in PHP and Perl versions.
The config_cfe Perl module contains functions that ease updating small text files, usually configuration files. It is easy to write small scripts that can do editing in 'batch mode', a necessary thing when updating many hosts at the same time. There is a simple program, update-cfe, that can be used in shell scripts (sometimes update-cfe is enough to update a section in a file).
WizardRMS is a collection of Perl CGI scripts for managing historical archives of application reports and other flat text files. It features cross-date/cross-report search capabilities, individual logins, plain English audit logs, per-report access restrictions, PDF report rendering, and CD-R daily archive backup.
ParaTools is a set of Perl modules for the handling of document references. It includes three citation parsers, two document parsers, OpenURL support, Web service examples, and detailed documentation. The toolkit has been designed to be easily expandable. The parsing functionality in ParaTools is already in use in the ParaCite system.
Unique ID is a Perl CGI that calculates and reverse engineers identification numbers. Given your name, birthday and gender, it will tell you your identification number. Given the number it will tell you your birthday, gender, and take educated guesses at your name. It currently supports driver's license numbers for Florida, Illinois, Maryland, Michigan, Minnesota, New Hampshire, New York (pre-1992), Washington, and Wisconsin. It also supports the MRZ portion of a modern U.S. passport.
