% 2. Sources:
%     (a) Original source: unknown
%         -- NASA: Mr. Roger Burke's autolander design team
%     (b) Donor: Bojan Cestnik
%                 Jozef Stefan Institute
%                 Jamova 39
%                 61000 Ljubljana
%                 Yugoslavia (tel.: (38)(+61) 214-399 ext.287) 
%     (c) Date: November 1988

% 3. Past Usage: (several, it appears)
%      Example: Michie,D. (1988).  The Fifth Generation's Unbridged Gap.
%               In Rolf Herken (Ed.) The Universal Turing Machine: A
%               Half-Century Survey, 466-489, Oxford University Press.
% 
% 4. Relevant Information:
%      This is a tiny database.  Michie reports that Burke's group used
%      RULEMASTER to generate comprehendable rules for determining
%      the conditions under which an autolanding would be preferable to
%      manual control of the spacecraft.

% 8. Missing Attribute Values:
%    -- none
%    -- but several "don't care" values: (denoted by "*")
%          Attribute Number:   Number of Don't Care Values:
