Documentation for this Tcllib package can be found at: http://tcllib.sourceforge.net/doc/format.html , http://tcllib.sourceforge.net/doc/formatter.html , http://tcllib.sourceforge.net/doc/mpexpand.html .
The idea here is to include in tcllib a set of tools making it easier to write documentation. To that effort, a set of tools is included so that the tcllib author can write the documentation for his/her module in a format agnostic manner, and then convert the documentation into Unix man pages, HTML, and other formats.
The basis of the implementation is the expander package in textutil, a derivative of the expand macro processor.
