@ nbsparks -- glad it helped ... just remember always that whatever code shows up on this site, you definitely need to test first prior to using in production ...

dh_pysupport

DH_PYSUPPORT(1) 						  python-support						   DH_PYSUPPORT(1)

NAME

       dh_pysupport - use the python-support framework to handle Python modules

SYNOPSIS

       dh_pysupport [debhelper options] [-V X.Y] [-X item [...]] [-n] [module dirs ...]

DESCRIPTION

       dh_pysupport is a debhelper program that will scan your package, detect public modules in /usr/lib/pythonX.Y/site-packages, and move them
       to the shared Python modules location. It will generate appropriate postinst/prerm scripts to byte-compile modules installed there for all
       available python versions.

       It will also look for private Python modules and will byte-compile them with the current Python version. You may have to list the
       directories containing private Python modules.

       If a file named debian/pyversions exists, it is used to determine the python versions with which the package can work.

       Appropriate dependencies on python-support, python and pythonX.Y are put in ${python:Depends}.  The ${python:Versions} and
       ${python:Provides} optional substitution variables are made available as well.

OPTIONS

       module dirs
	   If your package installs private python modules in non-standard directories, you can make dh_pysupport check those directories by
	   passing their names on the command line. By default, it will check /usr/lib/$PACKAGE, /usr/share/$PACKAGE, /usr/lib/games/$PACKAGE and
	   /usr/share/games/$PACKAGE

       -n, --noscripts
	   Do not modify postinst/postrm scripts.

       -d  This option is deprecated.

       -V X.Y
	   Force private modules to be bytecompiled with the specific X.Y python version, regardless of the default python version on the system.

       -X item, --exclude=item
	   Exclude files that contain "item" anywhere in their filename from being taken into account to generate the python dependency. It also
	   excludes them from byte-compilation. You may use this option multiple times to build up a list of things to exclude.

CONFORMS TO

       Python policy as of 2006-08-10

SEE ALSO

       debhelper(7)

       This program is a part of python-support but is made to work with debhelper.
