From edae42d03385ad6cc80974f04021637d74f329af Mon Sep 17 00:00:00 2001 From: dholland Date: Sun, 4 Aug 2013 05:42:47 +0000 Subject: Add a curses gizmo for solving Sunday-paper-type cryptograms based on substitution ciphers. It gets the cleartext from fortune. I wrote this some years ago for my own amusement; a couple people have suggested that I should import it. Approved only by groo, so I'm going to wait a couple days to hook it to the build in case anyone demands it be removed again... --- cgram/cgram.6 | 64 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 cgram/cgram.6 (limited to 'cgram/cgram.6') diff --git a/cgram/cgram.6 b/cgram/cgram.6 new file mode 100644 index 00000000..36178d8d --- /dev/null +++ b/cgram/cgram.6 @@ -0,0 +1,64 @@ +.\" +.\" Copyright (c) 2004, 2013 The NetBSD Foundation, Inc. +.\" All rights reserved. +.\" +.\" This code is derived from software contributed to The NetBSD Foundation +.\" by David A.
