=head1 NAME

tmx-tokenize - tokenizes translation units on a tmx file.

=head1 SYNOPSIS

   tmx-tokenize file.tmx  # creates t_file.tmx

   tmx-tokenize -o=out.tmx file.tmx

=head1 DESCRIPTION

Although this script is bundled in C<XML::TMX>, it has a soft
dependency on C<Lingua::FreeLing3>. Soft means that the dependency is
not ensured at install time, and other features of the module can
still be used without C<Lingua::FreeLing3>. Nevertheless, if you want
to use this tool you should install that module.

At the moment the supported languages are the same as supported by
FreeLing3: English, Spanish, Russian, Portuguese and Italian.

It your TMX file includes any other language, they will be maintained
without a change.  This behavior can change in the future, as a basic
regexp based tokenizer might be implemented.
