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.
ParaTools is a set of Perl modules for the handling of document references.

The parsing functionality in ParaTools is already in use in the ParaCite system.
