tgen generates a Web site from a collection of input files of a
variety of types, using a set of registered HTML autogenerators. This
allows, for example, the generation a Web site consisting of plain
text pages, EtText formatted files, man or POD documentation, and/or
custom formats, with a consistent and attractive look-and-feel. It is
a driver program; the actual conversion work is done by a set of
plugin filters or "autoformatters" (named *2hts[.*]).
