+Subject:    a compiler test
+Date:        3 Mar 1992 12:31:00 GMT
+
+Will,
+   One of the decisions taken at the FLARE meeting yesterday was that we 
+(FLARE people) should send you (GRASP people) interesting Haskell programs 
+to test your new compiler. So allow me to present the following program, 
+written by Colin Runciman in various functional languages over the years,
+which puts propositions into clausal form. The original program was 
+interactive, but I've made it batch so that you can run it over night.
+Here is an example run with the prototype compiler. Note the result is 
+"a <=".
+
+	hc clausify.hs
+	Haskell-0.41 (EXPERIMENTAL)
+	Glasgow University Haskell Compiler, version 0.41
+	G-Code version
+	-71$ a.out
+	a <= 
+	-71$
+
+Cheers,
+
+David
