=head1 NAME

po4a-normalize - normalize a documentation file by parsing it in po4a, and writing it back

=head1 SYNOPSIS

po4a-normalize -f E<lt>fmtE<gt> E<lt>master.docE<gt>

=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 C<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 po4a-normalize.output while the
generated po file will be written to po4a-normalize.po. No way to change
that ;)

=head1 OPTIONS

=over 4

=item -o, --option

=item -h, --help

Show a short help message.

=item --help-format

List the documentation format understood by po4a.

=item -f, --format
