# Description: manage Python public modules build
#   This class is designed to work with Python packages using the
#   'distutils' build system and comply to the new policy established
#   during summer 2006.  Use of the debhelper class to make use of the
#   new dh_python is strongly advised.  (This is still left as optional
#   in line with CDBS' flexible behavior.)

# This class provides rules for old and new Python policy.  Leaving
# DEB_PYTHON_SYSTEM unset selects the old behavior.  The pysupport and
# pycentral methods are available to comply with new policy.  Don't forget
# to update your 'debian/control'.  (Build-Depends are correctly generated
# if you are using the auto control generation feature.)

# Once all old-style packages are removed before etch, some of the old
# can be refactored or removed.
