=head1 NAME
dh_python-ply - generate versioned dependencies on python-ply
=cut
use strict;
use warnings;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_python-ply> [B<--dependency-field> I<dependencyfield>] [S<I<debhelper options>>] I<file>...
=head1 DESCRIPTION
B<dh_python-ply> is a debhelper program that is responsible for generating the
B<python-ply:Depends> substitutions and adding them to substvars files.
The program will look only at Python modules that are explicitly provided as
its arguments, and will use this information to generate a strict versioned
dependency on B<python-ply>.
=head1 OPTIONS
=over 4
=item B<--dependency-field> I<dependencyfield>
Use B<python-ply:>I<dependencyfield> substitution variable instead of
B<python-ply:Depends>.
