=head1 NAME

Locale::Po4a::Docbook - convert DocBook XML documents from/to PO files

=head1 DESCRIPTION

The po4a (PO for anything) project goal is to ease translations (and more
interestingly, the maintenance of translations) using gettext tools on
areas where they were not expected like documentation.

Locale::Po4a::Docbook is a module to help the translation of DocBook XML
documents into other [human] languages.

=head1 STATUS OF THIS MODULE

This module is fully functional, as it relies in the L<Locale::Po4a::Xml>
module. This only defines the translatable tags and attributes.

The only known issue is that it doesn't handle entities yet, and this includes
the file inclusion entities, but you can translate most of those files alone
(except the typical entities files), and it's usually better to maintain them
separated.

=head1 OVERRIDE THE DEFAULT BEHAVIOR WITH COMMAND LINE OPTIONS

The default behavior of system provided modules is set to be on the safe side.

For example, the default of B<< <author> >> tag is aiming it to appear under
B<< <para> >>.  But you may be using it only under B<< <bookinfo> >>.  For this
case, you may want to translate it independently for each author.

If you don't like the default behavior of the xml module and its derivative
modules, you can provide command line options to change their behavior.  For
example, you can add the following to the po4a configuration file:

  opt:"-k 0 -o nodefault=\"<bookinfo> <author>\" \
            -o break=\"<bookinfo> <author>\" \
            -o untranslated=\"<bookinfo>\" \
            -o translated=\"<author>\""

This overrides the default behavior for B<< <bookinfo> >> and B<< <author> >>,
set B<< <bookinfo> >> and B<< <author> >> to break input data stream on these
tags, set B<< <bookinfo> >> not to translate its tagged content, and set B<<
<author> >> to translate its tagged content.
