"free form" document preparation system

 AFT is a document preparation system. It is mostly free form meaning that there
 is little intrusive markup. AFT source documents look a lot like plain old
 ASCII text.
 AFT has a few rules for structuring your document and these rules have more to
 do with formatting your text rather than embedding commands.
 Right now, AFT produces pretty good (weblint-able) HTML, XHTML, LaTeX, lout and
 RTF. It can, in fact, be coerced into producing all types of output (e.g.
 roll-your-own XML). All that needs to be done is to edit a rule file. You can
 even customize your own HTML rule files for specialized output.
