This code builds two things:



a) The CPDF PDF command line tool for editing PDF files.



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



[https://coherentpdf.com/cpdf/](https://coherentpdf.com/cpdf/)



Prerequisites to build

----------------------



The OCaml compiler



[http://ocaml.org](http://ocaml.org)



The camlpdf library



[http://github.com/johnwhitington/camlpdf](http://www.github.com/johnwhitington/camlpdf)



The ocamlfind library manager



[http://projects.camlcity.org/projects/findlib.html](http://projects.camlcity.org/projects/findlib.html)



If you are using the OPAM package manager:



[http://opam.ocamlpro.com](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 "v2.7". 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.
