+to give the glyph a unique name.  To do that, we define
+@code{\\savesymbol@{XXX@}}, which renames a symbol from @code{\\XXX} to
+@code{\\origXXX}, and @code{\\restoresymbols@{yyy@}@{XXX@}}, which renames
+@code{\\origXXX} back to @code{\\XXX} and defines a new command,
+@code{\\yyyXXX}, which corresponds to the most recently loaded version of
+@code{\\XXX}.")
