=head1 NAME
po4a-normalize - normalize a documentation file by parsing it in po4a, and writing it back
=head1 SYNOPSIS
B<po4a-normalize> B<-f> I<fmt> I<master.doc>
=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.
The B<po4a-normalize> script is a debugging tool used to make sure that
po4a don't change the document when it's not supposed to. Only use it if
you're developing a new module, or if you doubt the sanity of the tools.
The generated document will be written to F<po4a-normalize.output> while the
generated POT file will be written to F<po4a-normalize.po> by default, but
you can use the B<--localized> and B<--pot> options to change that.
=head1 OPTIONS
=over 4
=item B<-o>, B<--option>
Extra option(s) to pass to the format plugin. See the documentation of each
plugin for more information about the valid options and their meanings. For
example, you could pass '-o tablecells' to the AsciiDoc parser, while the
text parser would accept '-o tabs=split'.
=item B<-w>, B<--width>
Column at which we should wrap the resulting file if the format supports it
(default: 76).
=item B<-b>, B<--blank>
Create a blank translated document.
The generated translated document will be generated assuming all messages
are translated by a space or new line.
This is useful to check what parts of the document cannot be translated.
Both B<--blank> and B<--capitalize> can't be specified at the same time.
=item B<-C>, B<--capitalize>
Create a translated document and corresponding po-file with original strings
translated as their capitalized versions.
This is useful to check what parts of the document cannot be translated and
generate test data for po4a.
Both B<--blank> and B<--capitalize> can't be specified at the same time.
=item B<-h>, B<--help>
Show a short help message.
=item B<--help-format>
List the documentation formats understood by po4a.
=item B<-f>, B<--format>
Format of the documentation you want to handle. Use the B<--help-format>
option to see the list of available formats.
=item B<-M>, B<--master-charset>
Charset of the file containing the document to translate.
=item B<-l>, B<--localized>
Name of the normalized file to produce (I<po4a-normalize.output> by default).
=item B<-p>, B<--pot>
Pot file to produce (I<po4a-normalize.po> by default).
=item B<-V>, B<--version>
Display the version of the script and exit.
