=head1 NAME

nat-codify - Command line tool to codify corpora

=head1 SYNOPSIS

   nat-codify <file1.nat> <file2.nat>

   nat-codify -tmx <file.tmx>

=head1 DESCRIPTION

The C<-tokenize> flag can be used to force NATools to tokenize the
texts. Note that at the moment a Portuguese tokenizer is used for all
languages. This might change in the future.

The C<-id=name> flag can be used to force NATools Corpora name. By default
the name is read interactively.

The C<-q> flag can be used to force quite mode.
In thic case, the name is extracted from the file-names.

The C<-lang=PT..EN> flag can be used to force languages.
