Yodl is a package that implements a pre-document language and tools to
process it.  The idea of Yodl is that you write up a document in a
pre-language, then use the tools (eg. yodl2html) to convert it to some
final document language.  Current converters are for HTML, ms, man, LaTeX
SGML and texinfo, plus a poor-man's text converter.  Main document types
are "article", "report", "book" and "manpage".  The Yodl document
language is designed to be easy to use and extensible.
