The elisp function ocaml-refman-fontificato below is what I used to
use to browse ocaml docs.  In my experience, this is order of
magnitude faster than using a web browser with the html docs.

This code uses the function Man-fontify-manpage which is not
documented.  It works in GNU Emacs 19.34.

(if (string-match "XEmacs" emacs-version)

    (defun sposta-il-cursore-fuori ()
      (interactive)
      (set-mouse-pixel-position (frame-root-window)
                                30 ;(- (frame-pixel-width) 50)
                                -45))

    (defun sposta-il-cursore-fuori ()
      (interactive)
      (set-mouse-position (window-frame (frame-selected-window))
			  (1+ (frame-width))
                          0))
    )

(defun find-file-read-only-other-frame-fontificato (filename)
  (interactive "fFile to view: ")
  (require 'man)
  (find-file-read-only-other-frame filename)
  (toggle-read-only)
  (Man-fontify-manpage)
  (not-modified)
  (toggle-read-only))

(defun ocaml-refman-fontificato ()
  (interactive)
  (find-file-read-only-other-frame-fontificato
   "/usr/local/lib/ocaml/Doc/ocaml-refman.prn")
  (sposta-il-cursore-fuori))

Also, there's a little bug in caml.el.  Patch follows.
