+Here is a description of the source and licensing for the three word
+lists included in the wordgame package:
+
+words.txt
+=========
+ This file contains the OWL2+LWL lexicon as contained in Michael
+ Thelen's excellent zyzzyva program, available under the GPL from
+ http://www.zyzzyva.net/
+
+ Michael has the following to say about the lexicon:
+
+ Zyzzyva's OWL2+LWL lexicon is 100% accurate as verified by the
+ metrics available on the NSA Dictionary Committee's
+ website[*]. Zyzzyva has been used successfully as a Word Judge at
+ many North American SCRABBLE® tournaments, including BAT,
+ Oregon TILE, and the 2006 U.S. SCRABBLE® Open!
+
+ http://www.scrabble-assoc.com/boards/dictionary/octwl2.html
+
+ The relevant information from the dictionary committee website is as
+ follows:
+
+ If you're not sure you have the correct version of the digital
+ file, here are some statistics you can check. There are
+ currently 101 2-letter words, 1015 3, 4030 4, 8938 5, 15788 6,
+ 24029 7, 29766 8, 29150 9, 22326 10, 16165 11, 11417 12, 7750
+ 13, 5059 14 and 3157 15. The master file lists all words in
+ lower case in alphabetical order, one per line, with each line
+ terminated by a Unix line break. It is 1763167 bytes long and
+ has BSD checksum ('cksum -o 1') 12722, System V checkum
+ ('cksum -o 2') 24638, 32-bit CRC ('cksum -o 3') 2022312244,
+ ISO/IEC 8802-3:1989 checksum ('cksum') 427611949 and MD5
+ checksum dfd408f47cc1a324eb0ab5577910e4e3.
+
+ I (Carl Worth) have verified the contents of words.txt as included
+ in the wordgame package with resepct to the word counts listed
+ above as well as the MD5 checksum.
+
+obscure.txt
+===========
+ I created this file from both words.txt and 2of12inf.txt (described
+ below). It consists of words which appear in OWL2+LWL but that do
+ not appear in 2of12inf.txt. Note that this list does not include
+ the 1083 2-15 letter words that appear in 2of12inf.txt but not in
+ OWL2+LWL nor does it contain the 832 words in 2of12inf.txt that
+ have more than 15 letters.
+
+ For the purposes of generating obscure.txt, the plurals of
+ uncountable nouns marked with % are considered as included in
+ 2of12inf.txt, (that is, they are not considered obscure).
+
+2of12inf.txt
+============
+ This word list is the result of an attempt to create a list of
+ common English words suitable for use in a word game. The list is
+ the result of efforts by Kevin Atkinson and Alan Beale. The list
+ was obtained as part of the 12dicts package from:
+
+ http://wordlist.sourceforge.net/12dicts-readme.html
