CamlPDF project is an OCaml library for reading, writing and manipulating Adobe portable document files. It is presented as a literate program in the manner of Knuth. Since this is an implementation of someone else's technology (unlike the rest of our work, which is new), we have decided to release it for wider use.
CamlPDF consists of a set of low level modules for representing, reading and writing the basic structure of PDF, together with an initial attempt at a higher level API.
CamlPDF is released under a BSD licence with special exceptions. See the LICENCE file in the source for details.
