libppxlib-ocaml-dev - 0.27.0-2+b1 main

The ppxlib project provides the basis for the ppx system, which is
currently the officially supported method for meta-programming in
OCaml. It offers a principled way to generate code at compile time in
OCaml projects. It features:
* OCaml AST / parser / pretty-printer snapshot, to create a full
frontend independent of the version of OCaml;
* library for ppx rewriters in general, and type-driven code
generators in particular;
* feature-full driver for OCaml AST transformers;
* quotation mechanism allowing to write values representing the
OCaml AST in the OCaml syntax;
* generator of open recursion classes from type definitions.
