You should use B<dh_python2> instead. -This program will do nothing if F<debian/pycompat> or a -B<Python-Version> F<control> file field exists. - -B<dh_python> is a debhelper program that is responsible for generating the -B<${python:Depends}> substitutions and adding them to substvars files. It -will also add a F<postinst> and a F<prerm> script if required. - -The program will look at Python scripts and modules in your package, and -will use this information to generate a dependency on B<python>, with the -current major version, or on B<python>I<X>B<.>I<Y> if your scripts or modules need a -specific B<python> version. The dependency will be substituted into your -package's F<control> file wherever you place the token B<${python:Depends}>. - -If some modules need to be byte-compiled at install time, appropriate -F<postinst> and F<prerm> scripts will be generated. If already byte-compiled -modules are found, they are removed. - -If you use this program, your package should build-depend on B<python>. - -=head1 OPTIONS - -=over 4 - -=item I<module dirs> - -If your package installs Python modules in non-standard directories, you -can make F<dh_python> check those directories by passing their names on the -command line.
