## How we generate the formats

This manual is written in XML using the » DocBook XML DTD, using » XSLT (Extensible Stylesheet Language Transformations) for maintenance and formatting.

Using XML as a source format gives the ability to generate many output formats from the source files, while only maintaining one source document for all formats. The tools used for formatting the online manual are » xsltproc and » DocBook XSL Stylesheets. The HTML and TeX versions use » Jade, written by » James Clark; and » The Modular DocBook Stylesheets, written by » Norman Walsh. We use » Microsoft HTML Help Workshop to generate the Windows HTML Help format of the manual, and of course PHP itself to do some additional conversions and formatting.

The PHP manual is generated in various languages and formats, see » http://www.php.net/docs.php for additional details. The XML source code may be downloaded from CVS and viewed at » http://cvs.php.net/. The documentation is stored in the phpdoc module.
