The granddaddy, (developed in 1966), of macro processors ML/I is also free
and ported to many platforms.  I'm currently evaluating which one I like
better myself, so far I am leaning towards ML/I because it has nested
if/then/else/end and do/while structures, and it lets you fully define the
syntax and delimiters of your "home-made" macro language.
