daps - A complete environment to build HTML, PDF, ePUB and other formats from DocBook XML.


daps -d DC-file [GLOBAL OPTIONS] subcommand [COMMAND OPTIONS]

daps --main MAIN-file [GLOBAL OPTIONS] subcommand [COMMAND OPTIONS]


DAPS contains a set of stylesheets, scripts and Makefiles that enable you to create HTML, PDF, ePUB and other formats from DocBook XML with a single command. It also contains tools to generate profiled source tarballs for distributing your XML sources for translation or review.

DAPS also includes tools that assist you when writing DocBook XML: linkchecker, validator, spellchecker, editor macros and stylesheets for converting DocBook XML.

Most of DAPS' functionality can be accessed with the command daps. Run daps help to access the built-in tool documentation. If you want information about a specific command, you can run daps subcommand help



Overwrite, define or delete an AsciiDoc document attribute. >To overwrite an attribute already defined in the AsciiDoc document, use NAME=VALUE, or just NAME for attributes without a value. To delete a value set in the document use NAME!. To set a value that is not already set in the document, use NAME=VALUE@.

Default: unset.

This option can be specified multiple times. Only works with AsciiDoc sources and is ignored otherwise.


Specify a directory for the images used in the AsciiDoc sources. Must contain all images, subdirectories are ignored. Not required if the images reside in the directory structure required for DocBook projects (see DAPS manual).

Default: unset.

Only works with AsciiDoc sources and is ignored otherwise.


Directory where every output DAPS generates will end up.

Default: DOC DIR/build/


By default errors, results, warnings and certain info messages are printed in color using bash color codes. Set to '0' to turn off colors.

Default: 1 (when the output does not go to a terminal, colored output will be disabled automatically).


Show a list of available DAPS sub commands.


Print debugging messages. Alternatively see the --verbosity options for an output that is better readable.

--docconfig=DC-FILE, -d DC-FILE

Path to doc config file to use. Mandatory unless there is only a single DC-FILE in the current directory or unless you have configured a default value (DOCCONF_DEFAULT) in ~/.config/daps/dapsrc.

Default: unset.

Note: Options --docconfig and --main exclude each other.


Fallback styleroot directories. Can only be used in conjunction with --styleroot. By default, the DocBook stylesheets are used as a fallback if custom styles for an output format are not present. With this option you can specify a list of alternative fallbacks (space separated absolute paths). The directories will be tested in the order specified, the first one that applies to the requested format, will be used. The original DocBook stylesheets will be used as a last resort. Useful if you have forks of your custom stylesheets.

Default: unset.


Force a rebuild of the document even when an up-to-date version exists.

--help, -h



Specify how many parallel jobs to use. Higher numbers will significantly increase the processing speed, but will also set your machine under heavy load, up to a point where it may become (temporarily) unresponsive.

Default: Use as man jobs as available CPU cores.

--main=FILE, -m FILE

Path to the main file defining your document.

Note: Options --main and --docconfig exclude each other.


URN to a DocBook 5 schema that is to be used for validation. Will be ignored when validating DocBook 4 documents. Note: To validate with a local schema, specify an absolute path with the file:// prefix (e.g. file:///foo/schema.rnc)


By default, DAPS uses the DocBook Stylesheets to create output. If you have your own set of stylesheets, specify the absolute path to the stylesheet directory here. The DocBook stylesheets will be used as a fallback in case styles are not defined for all output formats.

--verbosity=0, -v0

Verbosity Level 0 (print 1 line of results)

--verbosity=1, -v1, -v

Verbosity Level 1 (print intermediate results)

--verbosity=2, -v2, -vv

Verbosity Level 2 (print all files created)

--verbosity=3, -v3, -vvv

Verbosity Level 3 (print all commands, very verbose). Parallelization of jobs will be turned off, to increase the readability.


Print the version number


Specify an XSLT processor that is used to transform the XML files. Currently supported are "xsltproc" and "saxon" (version 6).

Default: xsltproc
