-This hook is necessary to handle inconsistencies in versions of and
-sources of the gnuplot info file.  If Gnuplot-mode can find the info
-file generated from the 3.6beta patchlevel 347 (or later) release of
-Gnuplot, then this hook probably is not necessary.  Some versions of
-the info file may have a General Index session, which can be used by
-info-look.  In that case the following (or something similar with the
-value of `info-lookup-symbol-alist' altered appropriately) should be
-placed in the .emacs file.

-Emacs version 20.2 ships with a different version of info-look that
-does 20.3.  If you use any version of Emacs 19, you must use the
-version from 20.2.  Any version of XEmacs 20 or 21 should use the
-version from 20.3 but can use either.  XEmacs 19 should use the
