10 ;;; What is this talk of 'release'? Klingons do not make software
11 ;;; 'releases'. Our software 'escapes', leaving a bloody trail of
12 ;;; designers and quality assurance people in its wake.
14 ;;; This organization and structure is new to the 21st Century
15 ;;; version.. Think, "21st Century Schizoid Man".
