It merges the new function into jQuery, meaning you can then apply all
of the library's methods to it. Try http://docs.jquery.com/Plugins/Authoring
if you haven't yet seen it.
I often write tiny add-ons in basic style, eg
function menutoggle ()
{
do stuff
};
But these only serve one purpose; they can't be 'plugged into' other
jQuery routines.
Steven Holzner's book on OOP has a section on extending; try
