libjson-static-camlp4-dev 0.9.8-1build3 (powerpc binary) in ubuntu trusty

 json-static is a tool for converting parsed JSON data
 with an unchecked structure into specialized OCaml
 types and vice-versa.
 .
 By reading a type definition, the preprocessor inserts
 code that converts between OCaml types and untyped
 JSON data.
 .
 Type definitions are written in a syntax which is
 very close to regular OCaml type definitions.
