#
# 1. Read word list
#       word list is long (over 200,000 words!) so we
#       just print the first 100; this goes away later
# 2. Eliminate words that are not exactly 5 characters long
# 3. Read pattern, characters that must be in the word ("good
#       letters"), characters that are not in the word ("bad
#       letters")
#       print them to verify they are right, and then quit;
#       this goes away later
