NAME

       po4a-build - build translated documentation

SYNOPSIS

       po4a-build [-f | --file FILE] [--pot-only]

       po4a-build [-? | -h | --help | --version]

DESCRIPTION

       po4a-build is intended to make it as easy to produce translated documentation as it can be
       to produce the current untranslated content.

       When po4a prepares the translated content as POD or DocBook XML, the final documentation
       can then be built using po4a-build. Both the untranslated and translated content is built
       as a single process, updating the POT files at the same time.

       Existing build instructions are replaced by a single call to po4a-build and a simple
       configuration file is used to tell po4a-build how to build each element and which binary
       packages will include the translated and untranslated content.

       Once built, the content will be in package-specific directories beneath the BASEDIR
       specified in the configuration file. For a binary package foo, with translations into
       German and French, this would result in:

           BASEDIR/foo/man/man1/foo.1
           BASEDIR/foo/man/de/man1/foo.1
           BASEDIR/foo/man/fr/man1/foo.1

       This makes it easy to include all the generated content into the binary package with a
       single install location:

           doc/foo/man/* ./usr/share/man/
           doc/foo/html/* ./usr/share/doc/foo/

       This rule will not need to be updated when new translations are added and adding a second
       binary package (bar) allows the content for that package to kept separate.

   Supported formats
       Currently, po4a-build supports the following combinations:

        1. DocBook XML for section 1.

        2. DocBook XML for section 3.

        3. DocBook XML for HTML.

        4. POD for section 1.

        5. POD for section 3.

        6. POD for section 5.

        7. POD for section 7.

       All supported formats, in all supported combinations, can be handled in a single
       po4a-build.conf configuration file and in a single call to po4a-build. See po4a-
       build.conf(5).

CONFIGURATION

       po4a-build uses a default configuration file, po4a-build.conf which should be in the top
       level directory of your package VCS. (Use the -f option to specify a different file.) See
       po4a-build.conf(5).

       Example 1. example configuration file

       An example configuration file is available at:

           /usr/share/doc/po4a/examples/po4a-build.conf.example

   configuration file layout
       The configuration file consists of several sections, general, XML/XSL support, POD support
       and HTML support.

       General includes the name and location of the po4a config file (probably best to leave
       this as po4a.config), the po directory containing the documentation PO files (often
       doc/po), the full name of the POT file used to create the translations, the BASEDIR for
       the generated output, whether the package contains manpages in section 3 rather than just
       section 1 and the names of the binary packages which are to contain the generated output.

       XML/XSL support includes specifying which of the binary packages use XSL support in the
       XMLPACKAGES variable, the top level DocBook file to pass to xsltproc and the location of
       the XML or DocBook files. The XSLFILE can be overridden, if necessary.

       POD support includes specifying which of the binary packages use POD support in the
       PODPACKAGES variable and the full name of the POD file.

       HTML support specifies the subdirectory to create below BASEDIR for the untranslated and
       translated HTML content and the DocBook file to generate the HTML. The HTMLXSL file can be
       overridden, if necessary.

COMMANDS

       --pot-only
           Only updates the POT file(s).  --pot-only is intended to support packages including
           all POT files in the package source. Packages using Autotools can easily add the POT
           file via EXTRA_DIST but packages just using a Makefile or certain VCS build helpers
           can find it awkward to add the POT file (which is a generated file) without putting
           the POT file into the VCS. To avoid this ugly and unnecessary work, po4a-build can
           update the POT file(s) at the start of the build, so that dpkg-source includes them
           into the source tarball.

           Example 2. svn-buildpackage example

           svn-buildpackage has explicit support for this kind of addition, using the
           useNativeDist SVN property and the native-dist Make target.

               # adds the POT file to the source tarball
               native-dist: Makefile
                    po4a-build --pot-only

               $ svn propset useNativeDist 1 debian

       -h|--help
           print the usage message and exit.

       --version
           print the usage message and exit.

OPTIONS

       -f|--file FILE
           Override the po4a-build default configuration file (po4a-build.conf) and supply your
           own.
