+  "Support library for Sail, a language for describing the instruction semantics of processors"
+description:
+  """The support library for instruction-set semantics generated from Sail.
+Sail is a language for describing the instruction-set
+architecture (ISA) semantics of processors. Sail aims to provide a
+engineer-friendly, vendor-pseudocode-like language for describing
+instruction semantics. It is essentially a first-order imperative
+language, but with lightweight dependent typing for numeric types and
+bitvector lengths, which are automatically checked using Z3. It has
+been used for several papers, available from
+http://www.cl.cam.ac.uk/~pes20/sail/.
+The Sail tool can be found in main opam repository."""
