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 (e.g. yodl2html) to convert it to some final document language. current converters are for html, man, latex sgml and texinfo, a poor-man's text converter and an experimental xml converter. main document types are "article", "report", "book", "manpage" and "letter". the yodl document language was designed to be easy to use and extensible.

this package provides the supplemental documentation for yodl.
