+=head1 NAME
+
+dh_python3-ply - generate versioned dependencies on python3-ply
+
+=cut

+
+=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>.
