This is `linuxdoc-tools', a series of tools to implement the Linux

Documentation Project HOWTO and book styles in SGML.

--

linuxdoc-tools is derived from linuxdoc-SGML, originally written by

Matt Welsh and later maintained by Cees de Groot. Linuxdoc-SGML is

based on James Clark's sgmls parser, and the QWERTZ DTD by Tom

Gordon. Magnus Alvestad provided the current HTML support. For

the rest of linuxdoc-SGML,

Original Linuxdoc-SGML itself does not have any limitations.

Everything not having explicit additional conditions can be freely

used, modified, and redistributed, under the usual fair use clauses:

 * No warranty. Use at your own risk.

 * Do not pretend to have written what you did not (Preserve credits

   and Copyright notices of the different elements if present).

Since then, lots of smaller and bigger changes resulted in a rename

to SGML-Tools (and then to SGMLtools, the hyphen caused confusion)

to indicate that it wasn't just for Linux anymore. See files

CHANGES.old-v1 and CONTRIBUTORS.old-v1 for changelog and list of

contributors to old linuxdoc-sgml and sgmltools-v1.

When sgml-tools dropped support for the linuxdoc DTD, Taketoshi Sano

<sano@debian.org> forked the code to linuxdoc-tools. See README file.
