This repo holds Simon Tatham's game Enigma, with some modifications by
me.  It's an awesome puzzle game.

Some of the mods are idiosyncratic things I don't expect anyone else to
want, such as the Makefile, but some others are things it would make
sense for others to want, such as the abort changes for save/restore.

The first commit in this repo is the code straight out of the tarball.
Everything beyond that is my work.
