Dear OCaml developers,
   Recently I found it was really neat to distribute your software (mostly binaries) in a single `.ml` file, easy to install(however fancy build systems and pre-processors you use does not affect your clients)  and potentially better inlining.
   The way I did is to use some internals from ocamldep to sort the list of files and concatenate them. But there is an issue about copy right header, since it is `comment`, I tried to use a named attribute node `ocaml.doc`, it works, but its output is not pretty, any suggestions? (maybe we should add a special attribute `ocaml.copyright`?)
