+description: """
+
+This library provides a lean alternative to the Format [1] module of
+the OCaml standard library. It aims to make it easy for users to do
+the right thing. If you have tried Format before but find its API
+complicated and difficult to use, then Pp might be a good choice for
+you.
+
+Pp uses the same concepts of boxes and break hints, and the final
+rendering is done to formatter from the Format module. However it
+defines its own algebra which some might find easier to work with and
+reason about. No previous knowledge is required to start using this
+library, however the various guides for the Format module such as this
+one [2] should be applicable to Pp as well.
