This code builds two things:

a) The CPDF PDF Command Line Tools, which are a popular commercial command line tool for editing PDF files.

b) cpdf as an OCaml library, for which documentation is here:

https://coherentpdf.com/cpdf/

Prerequisites to build

The OCaml compiler

http://ocaml.org

The camlpdf library

http://github.com/johnwhitington/camlpdf

The ocamlfind library manager

http://projects.camlcity.org/projects/findlib.html

If you are using the OPAM package manager:

http://opam.ocamlpro.com

these can be installed by:

opam install camlpdf

To build

If downloading from Github, obtain the correct source. This means choosing the tag for a particular version, such as "v2.5". The head of the master branch is unstable.

1. Type make to make the cpdf executable and the library

2. Type make install to install the OCaml cpdf library.

The cpdf executable should be manually placed somewhere suitable.

Alternatively, the library and command-line binary can be installed by

opam install cpdf

Documentation

The file cpdfmanual.pdf in this folder is the documentation for the command line tools. The documentation for the cpdf OCaml library is in doc/html/cpdf/ in this folder once the library has been built.
