+# Challenge 166
+#
+# Task 1: Hexadecimal Words
+# Submitted by: Ryan J Thompson
+#
+# As an old systems programmer, whenever I needed to come up with a 32-bit
+# number, I would reach for the tired old examples like 0xDeadBeef and
+# 0xC0dedBad. I want more!
+#
+# Write a program that will read from a dictionary and find 2- to 8-letter
+# words that can be "spelled" in hexadecimal, with the addition of the following
+# letter substitutions:
+#
+#     o -> 0 (e.g., 0xf00d = "food")
+#     l -> 1
+#     i -> 1
+#     s -> 5
+#     t -> 7
+#
+# You can use your own dictionary or you can simply open
+# ../../../data/dictionary.txt (relative to your script's location in our GitHub
+# repository) to access the dictionary of common words from Week #161.
+#
+# Optional Extras (for an 0xAddedFee, of course!)
+#
+#     Limit the number of "special" letter substitutions in any one result to
+#     keep that result at least somewhat comprehensible. (0x51105010 is an
+#     actual example from my sample solution you may wish to avoid!)
+#
+#     Find phrases of words that total 8 characters in length
+#     (e.g., 0xFee1Face), rather than just individual words.
