glaurung 2.2-2ubuntu2 (ppc64el binary) in ubuntu focal

 This is a very strong chess engine, finished 4th place at internatonal
 ChessWar X. It uses the UCI (universal chess interface), for chess
 engines as communication protocol. This means to play against it,
 you have to use an UCI capable interface, like knights. Or an
 xboard adapter like polyglot.
