# agrimstrup2007-10-25  Added file to ACS source tree and modified
#                       to make searching import behaviour an ACS
#                       default
# dmuders   2005-08-19  Ported to Python 2.4 for heuristics
# dmuders   2005-08-16  Walk through site directories in reverse order and
#			add new packages at the beginning of the search path to
#			make sure that the APEX packages override the others.
# dmuders   2003-08-08  Exchanged SOFTWARE_ROOTS / INTROOT setup in favor of
#			simply going through sys.path
# dmuders   2003-08-07  Created
