+* HOL Light.
+
+HOL Light is a computer program to help users prove interesting mathematical
+theorems completely formally in higher order logic. It sets a very exacting
+standard of correctness, but provides a number of automated tools and
+pre-proved mathematical theorems (e.g. about arithmetic, basic set theory and
+real analysis) to save the user work. It is also fully programmable, so users
+can extend it with new theorems and inference rules without compromising its
+soundness.
