NAME

       CamlP4 - Pre-Processor-Pretty-Printer for Objective Caml

SYNOPSIS

       camlp4 [load-options] [--] [other-options]

DESCRIPTION

       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).

       The Objective Caml compiler has a special option "-pp", allowing to call any preprocessor. If Camlp4 is used, the  parsing  is  done  (only
       once) by Camlp4, and the Objective Caml compiler resumes the rest of the compilation (typing, code generation).

       Camlp4  can  parse normal OCaml concrete syntax or any other user-definable syntax. As an example, an alternative syntax is provided, named
       Revised, because it tries to fix some problems of the original syntax.

       Camlp4 can pretty print the normal OCaml concrete syntax or the revised one (Pretty-Printer). It is therefore always  possible  to  have  a
       version of your sources compilable by the compiler Objective Caml without preprocessing.

       Camlp4 can also serve as a Program Transformation tool, the user can supply transformations and apply them easily as a pre-processing task.
       This is done with Filters.
