# Perl Weekly Challenge 076 Task #2 > Word Search
# Write a script that takes two file names. The first file would contain word
# search grid as shown below. The second file contains list of words, one
# word per line. You could even use local dictionary file.
#
# Print out a list of all words seen on the grid, looking both orthogonally
# and diagonally, backwards as well as forwards.
