+synopsis: "Preprocessor-pretty-printer of OCaml"
+description: """
+Camlp5 is a preprocessor and pretty-printer for OCaml programs. It also provides parsing and printing tools.
+
+As a preprocessor, it allows to:
+
+extend the syntax of OCaml,
+redefine the whole syntax of the language.
+As a pretty printer, it allows to:
+
+display OCaml programs in an elegant way,
+convert from one syntax to another,
+check the results of syntax extensions.
+Camlp5 also provides some parsing and pretty printing tools:
+
+extensible grammars
+extensible printers
+stream parsers and lexers
+pretty print module
+It works as a shell command and can also be used in the OCaml toplevel."""
