%  Test the raw tokanization of the  ScriptToken Subroutines
%
%  This actually uses very little of the magic core functions
%  and in fact creates a completely stand-alone program by substituting
%  required MagickCore with direct system equivelents.

%  Build
%     cc     script-token-test.c   -o script-token-test
