I need help getting Ocamlnet to work at a basic level.
I tried running the script from the command-like to more easily access
diagnostic output. What should the shebang line say? Right now I have the
following (mostly) paste of the demo script, plus shebang line; when I run
it from within apache I get an internal server error. (A copy of the command
line output follows the script).

open Netcgi
let text = Netencoding.Html.encode_from_latin1
(* This function encodes "<", ">", "&", double quotes, and Latin 1
characters as character entities. E.g. text "<" = "<", and
text "ä" = "ä" *)
(* Normally you would use a template system instead of this *)
let html_page (cgi:cgi) title html =
let out = cgi#out_channel#output_string in
out "\n";
out ("\n" ^ text title ^"
\n");
out html;
out "\n"
let main (cgi:cgi) =
cgi#set_header

(* You can buffer or not the output. If buffered you can rollback
(useful in case of error). You can replace Netcgi_cgi.run by
another connector entry point (FCGI, SCGI, AJP, Apache mod). *)

Netcgi_cgi.run ~output_type:(`Transactional buffered) main
