CircleMUD: licensing issues

[qweo]

Hello!

Can connoisseurs of DFSG terms tell, is CircleMUD license ( http://www.circlemud.org/license-faq.html ) DFSG-Free, and can i create package with it for main section of Debian archive?
Best regards,qweo.
P.S.: Please reply to me directly (my email is mr.qweo <at> gmail <dot> com), because i didn't subscribed to Debian lists...
