# Caveats:
# 
# 02/09/2001
# At this time, this method only copies the target path recursively, setting 
# ownership on the copied object and anything recursively copied to that of
# the parent object.
# In most cases this will suffice, but if you have subfolders under a target 
# path which have different owners, this method will break that ownership
# on the copied objects.
# This might be added later if I have the time and inclination to do so.
# A.S.
