camlp4-extra 3.11.1-3 (i386 binary) in ubuntu lucid

 Objective Caml (OCaml) is an implementation of the ML language,
 based on the Caml Light dialect extended with a complete
 class-based object system and a powerful module system in the
 style of Standard ML.
 .
 CamlP4 is a Pre-Processor-Pretty-Printer for Objective Caml. It
 offers tools for syntax (Stream Parsers and Grammars) and the
 ability to modify the concrete syntax of the language
 (Quotations, Syntax Extensions).
 .
 This package contains pre-linked executables and libraries for
 pre-processing and pretty-printing OCaml sources out of the box
 for various common needs.
