=head1 SYNOPSIS

B<dh_python3-ply> [B<--dependency-field> I<dependencyfield>] [S<I<debhelper options>>] I<file>...

=head1 DESCRIPTION

B<dh_python3-ply> is a debhelper program that is responsible for generating the
B<python3-ply:Depends> substitutions and adding them to substvars files.

The program will look only at Python3 modules that are explicitly provided as
its arguments, and will use this information to generate a strict versioned
dependency on B<python3-ply>.

=head1 OPTIONS

=over 4

=item B<--dependency-field> I<dependencyfield>

Use B<python3-ply:>I<dependencyfield> substitution variable instead of
B<python3-ply:Depends>.

        # PLY 3.2, 3.3 and 3.4 embeds the same version number (3.2) in parser tables.
