% This copy of TRUSS was created by the TRUSS generator program,                
% on an Sun UltraSparc, on May 15, 1997.                                        
%                                                                               
% The following are relevant excerpts from lp/data/readme (by David M. Gay):

% The column and nonzero counts in the PROBLEM SUMMARY TABLE below exclude      
% slack and surplus columns and the right-hand side vector, but include         
% the cost row.  We have omitted other free rows and all but the first          
% right-hand side vector, as noted below.  The byte count is for the            
% MPS compressed file; it includes a newline character at the end of each       
% line.  These files start with a blank initial line intended to prevent        
% mail programs from discarding any of the data.  The BR column indicates       
% whether a problem has bounds or ranges:  B stands for "has bounds", R         
% for "has ranges".
