A tool to create PDFs that are also OCaml bytecodes

The bytepdf tool allows you to take a PDF foo.pdf and an OCaml bytecode foo.byte and merges them into a file that is both a valid PDF and a valid bytecode.

bytepdf --bc foo.byte --pdf foo.pdf -o bar.pdf

The resulting file can both be read as a pdf and executed by the ocaml interpreter:

open bar.pdf
ocamlrun bar.pdf

Furthermore, if you open the PDF with Acrobat Reader, the PDF will contain the OCaml bytecode as a file attachment. For more details, you can read the help. For an explanation of how this work, consider looking at this abstract. The only current limitation is that the bytecode should not have been statically linked with C code.

Install
