A simple attempt at working out what files are in and out of a mod, and if its broken
import os, sys, string
import xml.dom.minidom as minidom
from struct import unpack
from itertools import chain
class File:
"""a file (type and path)"""
MAP = "map"

/* finds nearest ant to a destination in a maze.
You give it a (partial) map and it plots a route using naive BFS.
As you discover more obstacles you can call addWater() for them.
It makes extensive use of pre-allocated data for intermediate results,
so you must extract the path for each call to findNearestAnt() or you
lose it. */
