+/* X bogusly doesn't define the interpretations of any bits besides
+ModControl, ModShift, and ModLock; so the Interclient Communication
+Conventions Manual says that we have to bend over backwards to figure
+out what the other modifier bits mean.  According to ICCCM:
+- Any keycode which is assigned ModControl is a "control" key.
+- Any modifier bit which is assigned to a keycode which generates Meta_L
+or Meta_R is the modifier bit meaning "meta".  Likewise for Super, Hyper,
+etc.
+- Any keypress event which contains ModControl in its state should be
+interpreted as a "control" character.
+- Any keypress event which contains a modifier bit in its state which is
+generated by a keycode whose corresponding keysym is Meta_L or Meta_R
+should be interpreted as a "meta" character.  Likewise for Super, Hyper,
+etc.
+- It is illegal for a keysym to be associated with more than one modifier
+bit.
+This means that the only thing that emacs can reasonably interpret as a
+"meta" key is a key whose keysym is Meta_L or Meta_R, and which generates
+one of the modifier bits Mod1-Mod5.
+Unfortunately, many keyboards don't have Meta keys in their default
+configuration.  So, if there are no Meta keys, but there are "Alt" keys,
+emacs will interpret Alt as Meta.  If there are both Meta and Alt keys,
+then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to
+mean "Symbol," but that just confused the hell out of way too many people).
+This works with the default configurations of the 19 keyboard-types I've
+checked.
+Emacs detects keyboard configurations which violate the above rules, and
+prints an error message on the standard-error-output.  (Perhaps it should
+use a pop-up-window instead.)
