+%description
+Astring exposes an alternative `String` module for OCaml.  This module
+tries to balance minimality and expressiveness for basic, index-free,
+string processing and provides types and functions for substrings,
+string sets and string maps.
+
+Remaining compatible with the OCaml `String` module is a non-goal.  The
+`String` module exposed by Astring has exception safe functions,
+removes deprecated and rarely used functions, alters some signatures
+and names, adds a few missing functions and fully exploits OCaml's
+newfound string immutability.
