In this section, we will locate and download the software on the Internet.
OpenJade is an actively maintained open-source software project based
on the Jade package by James Clark.
Download the lastest stable release at:
http://openjade.sourceforge.net/
OpenJade also includes the OpenSP package and the TeX macros, jadetex and pdfjadetex
for converting files to dvi and pdf. The following programs are provided by this
package:
openjade
onsgmls
osgmlnorm
ospam
ospent
osx
To use jadetex and pdfjadetex for making
dvi, ps, and pdf, you must have
a working TeX (tex) installation. If you do not have TeX, check with your
Linux distribution for a binary package that can be downloaded and installed.
Otherwise, you can download the teTeX distribution
of TeX from:
http://www.tug.org/tetex/
The entities define representations for special or untypeable symbols or characters, including
mathematical symbols, and the entities that you may be familiar with from HTML. These entity
files need to be installed for a proper configuration.
ISOEnts.zip can simply be unzipped into the directory where the DocBook DTD
is unzipped without requiring anything else but
the files in isoENT-tar.gz are also needed. Again, the files in isoENT-tar.gz
are to be unzipped into the DocBook DTD directory (see next section on installing for details),
but the filenames end with ".ent" suffix. These will need to
be renamed to a ".gml" ending. You can do this manually, or you can download and use the file below, made by this
author, which contains the files of both ISOEnts.zip and isoENT-tar.gz:

SGMLtools-Lite is a frontend for openjade, jadetex, pdfjadex,
dvips, and other programs. It
provides a single command for generating all the formats possible with these tools. The
lastest release can be downloaded at:
http://sourceforge.net/projects/sgmltools-lite/
This package is optional, but does make things easier sometimes.
HTMLdoc is a free program for converting websites into Portable Document Format (pdf)
or PostScript (ps). For pdf, it creates
a tree of bookmarks that make navigation easy.
Both htmldoc and pdfjadetex output pdf files,
but in slightly different formats. Try both and see which turns out best for a particular docbook file. See quick links
below for download site.
You can download the lastest version of HTMLdoc
from Easy Software Products'
ftp site.
DocBook2X requires perl5 and the SGMLS.pm perl module, available at the Comprehensive
Perl Archive Network (CPAN). SGMLS.pm provides libraries and a program
called sgmlspl which translates DocBook files into other
formats by using specification files. The specification files are perl files that
provide the logic for the translation to a particular format.
