textproc/docbook 4.5p5 OpenBSD

DocBook is a DTD maintained by the DocBook Technical Committee of OASIS. It is particularly well suited to books and papers about computer hardware and software (though it is by no means limited to these applications).

Because it is a large and robust DTD, and because its main structures correspond to the general notion of what constitutes a "book", DocBook has been adopted by a large and growing community of authors writing books of all kinds.

DocBook is supported "out of the box" by a number of commercial tools, and there is rapidly expanding support for it in a number of free software environments.

This ports installs all versions of the DocBook SGML DTD from versions 3.x and 4.x, and the last major release on the 2.x branch. The XML versions include the latest one, and a few other commonly used revisions.

If you are creating a new document, always try to use the latest version of the DTD.
