The easiest way to install is to use OPAM. Install Opam, then, as a regular user, fetch and install an OCaml version and install Ocf. The whole can be done with the following opam commands:

$ opam init --compiler=4.12.0
$ opam update
$ opam install ocf

You can also install the preprocessor package:

$ opam install ocf_ppx

To build Ocf, you will need:

• OCaml >= 4.12.0,
• Yojson >= 1.7,
• ppxlib >= 0.23.0.

Get the sources from git repository:

$ git clone https://framgit.org/zoggy/ocf.git
