== Older History

The author of the C version, Matt Day, shipped versions up to 3.0a. He
dropped out of sight and hasn't posted a new version or patch since
1990.  He said: "I do not take credit for inventing the game, I once
saw it on an IBM, and wrote it for Unix in C".  It probably originated
as a DOS freeware game in the 1980s, but there's no trail of
evidence before Matt's version and nothing matching in surviving
DOS freeware archives.

(Matt wrote) Additions to v3.0a (game-wise):
Replaced '-p' option with 'p' command, to allow toggling of the highlighting
moves feature.  Pretty nice, I think.. thanks to Jim Prescott.

The 3.1 version featured better interrupt handling and the `p' suffix to
GREEDOPTS.

Before 5.0 this program used curses and terminfo, and supported a lot
of terminal types that have become extinct or vanishingly rare since the
end of the 20th century. Breadth of support was traded away to get a
small, clean, memory-safe Rust implementation.
