-class ProxyPlugins:
-    '''
-    This class does some magic so that all we need to do in
-    ServerConnection is do a self.plugins.hook() call
-    and we will call any plugin that implements the function
-    that it came from with the args passed to the original
-    function.
-
-    To do this, we are probably abusing the inspect module,
-    and if it turns out to be too slow it can be changed. For
-    now, it's nice because it makes for very little code needed
-    to tie us in.
-
-    Sadly, propagating changes back to the function is not quite
-    as easy in all cases :-/ . Right now, changes to local function
-    vars still have to be set back in the function. This only happens
-    in handleResponse, but is still annoying.
