+synopsis:
+  "Camlp4 is a system for writing extensible parsers for programming languages"
+description: """\
+It provides a set of OCaml libraries that are used to define grammars as well
+as loadable syntax extensions of such grammars. Camlp4 stands for Caml
+Preprocessor and Pretty-Printer and one of its most important applications is
+the definition of domain-specific extensions of the syntax of OCaml.
+
+Camlp4 was part of the official OCaml distribution until its version 4.01.0.
+Since then it has been replaced by a simpler system which is easier to maintain
+and to learn: ppx rewriters and extension points."""
