+--% resolveTT Rules
+
+-- These rules are applied only once at the outermost position of a term
+-- some things can't be done by term rewriting conveniently (e.g. set
+-- difference), so a form is created which is interpreted by
+-- resolveTTRed later. The meanings of these forms are:
+-- Incl(x,y): y if x is a member of y, failed otherwise
+-- SetEqual(x,y): x if y is a permutation of x, failed otherwise
+-- SetComp(x,y): x-y, if y is a subset of x, failed otherwise
+-- SetInter(x,y): intersection of x and y, if nonempty, failed otherwise
+-- SetDiff(x,y): x-y, if x and y have a nonempty intersection, failed ...
+
+-- These first rules will be expanded for each of MP, DMP and NDMP
