=head1 NAME
pod2thread - Convert POD data to the HTML macro language thread.
=head1 SYNOPSIS
B<pod2thread> [B<-chn>] [B<-s> I<style>] [B<-t> I<title>]
    [I<input> [I<output>]]
=head1 DESCRIPTION
B<pod2thread> is a front-end for L<Pod::Thread>.  It uses that module to
generate thread source from POD source.
I<input> is the file to read for POD source (the POD can be embedded in
code).  If I<input> isn't given, it defaults to STDIN.  I<output>, if given,
is the file to which to write the thread output.  If I<output> isn't given,
the output is written to STDOUT.
=head1 OPTIONS
=over 4
=item B<-c>, B<--contents>
Generate a table of contents as the first section of the resulting thread
file, with links to each top-level heading.
=item B<-n>, B<--navbar>
Generate a navigation bar at the top of the resulting thread file, with
links to each top-level heading.
=item B<-h>, B<--help>
Print out usage information and exit.
=item B<-s> I<style>, B<--style>=I<style>
In the generated thread source, include a reference to the style sheet
I<style>.  If this option is not given, no style sheet reference will be
included.
=item B<-t> I<title>, B<--title>=I<title>
Use I<title> as the title of the page rather than looking for a NAME section
in the POD document.
=back
=head1 DIAGNOSTICS
If B<pod2thread> fails with errors, see L<Pod::Thread> and L<Pod::Simple>
for information about what those errors might mean.  Internally, it can also
produce the following diagnostic:
=over 4
=item Unknown option: %s
(F) An unknown command line option was given.
=back
In addition, other L<Getopt::Long> error messages may result from invalid
command-line options.
