CamlGI code has been integrated into the Netcgi component
<https://gps.dynxs.de/wwwsvn/trunk/code/src/netcgi/?root=lib-ocamlnet2>
of OcamlNet-2 <https://gps.dynxs.de/openapps/svnindex.cgi>, please use
that instead.

You can find examples in the examples/ directory (add.ml is a very
simple one).  As for the specific example you desire, it is attached.
It is maybe a bit more complex that you expected because it
demonstrates additional features (text escaping, setting the header,
buffered output).

Hope it helps,
ChriS

open Netcgi

let text = Netencoding.Html.encode_from_latin1
  (* This function encodes "<", ">", "&", double quotes, and Latin 1
     characters as character entities.  E.g. text "<" = "&lt;", and
     text "ä" = "&auml;" *)

(* 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 "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0//EN\" \
        \"http://www.w3.org/TR/REC-html40/strict.dtd\">\n";

  out html;
  out "</body>\n</html>"

let main (cgi:cgi) =
  cgi#set_header
    ~cache:`No_cache
    ~content_type:"text/html; charset=\"iso-8859-1\""
    ();
  let foo = cgi#argument_value "foo"
  let html = match foo with
    | "1" -> "Yes"
    | "0" -> "No"
    | _ -> "Undefined" in
  html_page cgi foo html

(* 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). *)
