def hasextension(filename, ext, smartness=0):
# when smartness = 0 filename is treated as uninterpreted bytestring
# when smartness = 10, filename will be:
# - unicode normalization
# - case normalization
# - accent normalization
# - synonym normalization
# - language normalization (have filename in French?)
# - mistyping normalization
# - extension normalization ('.jpg' matches '.jpg' and '.jpeg')
# - wrapper normalization (.tgz is normalized to .tar.gz)
# - filetype normalization (.mpg matches .mov, .avi, .ogg, etc)
... magic code follows ...
