"This article explains what DocBook is and how to create a
simple document using DocBook. Joe Brockmeier walks you
through creating a document and using SGML-tools Lite to parse the
document and make HTML, PostScript, plain-text, and PDF versions of
the document. He also includes further references on DocBook and
tips on where to find SGML-tools lite and other DocBook tools."
"DocBook is a markup language defined by an SGML or XML document
type definition (DTD). Basically, DocBook is a set of tags that
describe a document's structure. DocBook tags are similar to HTML
tags, so if you've done any HTML, then DocBook won't be entirely
foreign to you. DocBook is a bit more involved than HTML, but it is
also much more useful than plain HTML because it facilitates the
rendering of multiple formats from a single document. This article
will describe how to create a simple article (document) in DocBook
and how to use SGML-tools Lite to render several types of
file-formats from that document."
"DocBook has been around, in one form or another, since 1991.
Originally DocBook was created to help exchange UNIX documentation.
Since then DocBook gone through four major versions and now is
under the guidance of the Organization for the Advancement of
Structured Information Standards, better known as OASIS...."
"Occasionally, the term DocBook is also used as a catchall term
to describe the markup language and the tools used to convert
DocBook documents into other formats. Technically, DocBook is only
the DTD, but without SGML-tools Lite and other conversion tools
DocBook isn't quite as useful."
