+
+I (BigOrno) have written the initial [xrick](http://www.bigorno.net/xrick/) code.
+However, graphics and maps and sounds are by the authors of the original Rick Dangerous
+game, and "Rick Dangerous" remains a trademark of its owner(s) -- maybe
+Core Design (who wrote the game) or FireBird (who published it).
+As of today, I have not been successful at contacting Core Design.
+
+This makes it a bit difficult to formally release the whole code,
+including data for graphics and maps and sounds, under the terms of
+licences such as the GNU General Public Licence. So the code is
+released "in the spirit" of the GNU GPL. Whatever that means.
