TemplateGenerator, or TGen for short, is a command line tool for generating files based on information in a property list file. This tool is just an extremely generalized version of EOReporter, working with simple plist files, instead of a model.
TGen was initially designed to be able to produce resumes in HTML from data in a plist, but it's uses are strictly limited by your imagination. For example, the Rubicode site itself can be easily generated using TGen.
TGen can be compiled and used on MacOS X 10.x, MacOS X Server 1.2, WebObjects/NT, and OPENSTEP. It comes with source code. It is a loose descendant of EOGenerator and EOReporter.
