Simple preprocessor for OCaml
Cppo is an equivalent of the C preprocessor targeted at the OCaml language
The main purpose of cppo is to provide a lightweight tool for simple macro substitution #define and file inclusion #include for the occasional case when this is useful in OCaml. Processing specific sections of files by calling external programs is also possible via #ext directives.
The implementation of cppo relies on the standard library of OCaml and on the standard parsing tools Ocamllex and Ocamlyacc, which contribute to the robustness of cppo across OCaml versions.
