-
-The usual form for an engraver is an association list (or alist)
-mapping symbols to either anonymous functions or to another such
-alist.
-
-@code{make-engraver} accepts forms where the first element is either
-an argument list starting with the respective symbol, followed by the
-function body (comparable to the way @code{define} is used for
-defining functions), or a single symbol followed by subordinate forms
-in the same manner. You can also just make an alist pair
-literally (the @samp{car} is quoted automatically) as long as the
-unevaluated @samp{cdr} is not a pair. This is useful if you already
-have defined your engraver functions separately.
-
-Symbols mapping to a function would be @code{initialize},
-@code{start-translation-timestep}, @code{process-music},
-@code{process-acknowledged}, @code{stop-translation-timestep}, and
-@code{finalize}. Symbols mapping to another alist specified in the
-same manner are @code{listeners} with the subordinate symbols being
-event classes, and @code{acknowledgers} and @code{end-acknowledgers}
-with the subordinate symbols being interfaces."
