# custom version of the now deprecated find module 
# in the standard library--import as "PyTools.find";
# equivalent to the original, but uses os.path.walk,
# has no support for pruning subdirs in the tree, and
# is instrumented to be runnable as a top-level script;
# results list sort differs slightly for some trees;
# exploits tuple unpacking in function argument lists;
