#   NOTE From Dennis J. Darland (11/2/2015)
#
#   I obtained the "c" language source code for "russell" copyrighted above
#   in the 1990's. I have made efforts to get it to work over the years, but
#   always failed. It has many hardware and OS dependancies. Now (October 2015
#   forward, I am tring to port to the language "Unicon". Practically every
#   line of code will need to be changed, as someing as simple as the
#   assignment operator is different. Also I will not use the BigNum package
#   mentioned above. Also I am doing this not for profit, and am sharing
#   freely. I am not at all confident that I will get it working well, but
#   believe in open source, so am sharing my work as I make progress.
#   Unicon is also much more portable.
