# ignore_patterns and copytree funtions are copies of what is included
# in shutil.copytree of python v2.6 and later.
#
### When compatibility is no-longer needed, this block
### can be replaced with:
###
###     from shutil import ignore_patterns, copytree
###
### or the "shutil." qualifier can be prepended to the function
### names where they are used.
