converts man/mdoc/ms/me/mm documents to DocBook
The doclifter program translates documents written in troff macros to DocBook.
Lifting documents from presentation level to semantic level is hard, and
a really good job requires human polishing. This tool aims to do everything
that can be mechanized, and to preserve in XML comments any troff-level
information that might have structural implications. Also includes manlifter,
a driver script that can be used to convert entire manual-page hierarchies.
