-/*
- *	"enigma.c" is in file cbw.tar from
- *	anonymous FTP host watmsg.waterloo.edu: pub/crypt/cbw.tar.Z
- *
- *	A one-rotor machine designed along the lines of Enigma
- *	but considerably trivialized.
- *
- *	A public-domain replacement for the UNIX "crypt" command.
- *
- *	Upgraded to function properly on 64-bit machines.
