=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 PO file will be written to F<po4a-normalize.po>. No way to change
that ;)

=head1 OPTIONS

=over 4

=item B<-o>, B<--option>

Extra option(s) to pass to the format plugin. Specify each option in the
'I<name>B<=>I<value>' format. See the documentation of each plugin for more
information about the valid options and their meanings.

=item B<-b>, B<--blank>

Create an 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.

=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<-V>, B<--version>

Display the version of the script and exit.
