ATD stands for Adaptable Type Definitions. It is a syntax for defining
cross-language data types. It is used as input to generate efficient
and type-safe serializers, deserializers and validators. The current target
languages are OCaml and Java.

The following opam packages are provided by the atd project:

• atdgen: executable that generates OCaml code dealing with json and
  biniou data formats

• atdj: executable that generates Java code dealing with json

• atd: library for parsing atd files used by code generators
