function gcompare(s1,s2)
% GCOMPARE :    GCOMPARE ( [ 'file1' ; 'file2' ] , [ 'var1' ; 'var2' ...] )
%               This optional command plots the trajectories of a list of
%               variables in two different simulations. One plot is drawn
%               for each variable. The trajectories must have been previously
%               saved by the instruction DYNASAVE. The simulation in file1
%               is refered to as the base simulation.
