### H.4 Using the Emacs Info Reader for Octave

You may also use the Emacs Info reader with Octave’s `doc` function. For this, the package `gnuserv` needs to be installed.

If `gnuserv` is installed, add the lines

    (autoload 'octave-help "octave-hlp" nil t)
    (require 'gnuserv)
    (gnuserv-start)

to your `.emacs` file.

You can use either ‘plain’ Emacs Info or the function `octave-help` as your Octave info reader (for ‘`help -i`’). In the former case, use `info_program ("info-emacs-info")`. The latter is perhaps more attractive because it allows to look up keys in the indices of several info files related to Octave (provided that the Emacs variable `octave-help-files` is set correctly). In this case, use `info_program ("info-emacs-octave-help")`.

If you use Octave from within Emacs, it is best to add these settings to your `~/.emacs-octave` startup file (or the file pointed to by the Emacs variable `inferior-octave-startup-file`).
