address@hidden variable, it is recommended that you upgrade

address@hidden Hyperbole
address@hidden hyperb:version
-Users of Bob Weiner's Hyperbole package take note.  Hyperbole provides
-the necessary overloads (and a whole lot more!) and you can potentially
-clobber it if you were to load Supercite's overloading after
-Hyperbole's.  For this reason, Supercite will @emph{not} perform any
-overloading if it finds the variable @code{hyperb:version} is
address@hidden (i.e. it exists because Hyperbole has been loaded into
-your Emacs session).  If this is the case, Supercite will display a
-warning message in the minibuffer.  You should consult the Hyperbole
-manual for further details.
-
-Overloading involves the re-definition of the citing function with the
-new, @code{mail-citation-hook} savvy version.  The function in
address@hidden that does this is @code{sc-perform-overloads}.  This
-function is smart enough to only overload the MUA functions when it is
-absolutely necessary, based on the version numbers it can figure out.
-Also, @code{sc-perform-overloads} will only install the new functions
-once.  It is also smart enough to do nothing if the MUA is not yet
address@hidden
-
-The tricky part is finding the right time and place to perform the
-overloading.  It must be done after the MUA has been loaded into your
-Emacs session, but before the first time you try to yank in a message.
-Fortunately, this has been figured out for you.
-
-If you must overload, you should put the following lisp code in your
address@hidden file, to make sure the @file{sc-oloads.el} file gets
-loaded at the right time:
-
address@hidden
-(autoload 'sc-perform-overloads "sc-oloads" "Supercite 3.1" t)
