linuxdoc-tools 0.9.21 (i386 binary) in ubuntu warty

SGML converters for the LinuxDoc DTD only.
 LinuxDoc is a kind of SGML DTD. It was created for
 the Linux HOWTOs, and had been used officially by
 the Linux Documentation Project (LDP). Now LDP has
 aggressively migrated into the DocBook world, but many
 documents are still available in LinuxDoc DTD sgml.
 So users may still need the tool for LinuxDoc, therefore
 LinuxDoc-Tools was created on the basis of sgml-tools_v1.
 .
 The main command is linuxdoc, and -B option is provided
 to choose the proper backend driver for desired output.
 linuxdoc -B check: for syntax checking
 linuxdoc -B html: conversion to html
 linuxdoc -B info: conversion to info
 linuxdoc -B latex: conversion to latex, dvi, and postscript
 linuxdoc -B lyx: conversion to lyx
 linuxdoc -B rtf: conversion to rtf
 linuxdoc -B txt: conversion to text
 .
 HTML can be generated without any other Debian text
 processing package, but for the other formats the
 appropriate packages will have to be installed.
  - Text conversion requires groff
  - LaTeX conversion requires tetex-base, tetex-bin, and tetex-extra
  - Info conversion requires texinfo
 You can install linuxdoc-tools-text for required dependency of
 text conversion. linuxdoc-tools-latex and linuxdoc-tools-info
 are provided for dependencies of latex or info conversion.
 .
 This linuxdoc-tools has been designed and implemented only
