# This script searches a file (either archetypes or maps) for certain
# desired values.   It is better than grep in that it keeps track of the
# the archetype it occurs in and does smarter searches (ie, certain
# bitmask values you can search for specific bit sets, which is not
# easy to do with grep)
#
# Originally written to find all the creatures that use ghosthit.
# Modified to find all object types that are being set invisible
# in pupland
