=head1 NAME

sentences - Command line tool for text segmentation, tokenization and annotation

=head1 SYNOPSIS

   sentences [-tokenize[=cqp]] [-nat] [-o=output] <file>
  
=head1 DESCRIPTION

C<sentences> is a command line tool for text segmentation and annotation. It uses the
C<fsentences> function from C<Lingua::PT::PLNbase>. Its main behaviour is the detection of
sentences and paragraphs, and their annotation with XML-like tags: E<lt>sE<gt> for sentences, 
E<lt>pE<gt> for paragraphs, and E<lt>textE<gt> for different files.

If the flag C<-tokenize> is used, then words are detected and separated from each other by a
space. If C<-tokenize=cqp> is used, then each token is placed in a line by itself.

The C<-nat> flag can be used to force a non-XML output, used for NATools alignment tools.

It is also possible to use the C<-o> flag to send the output to a specific file.
