Flamenco notations

[Oscar van Eijk]

Hi all,

I've seen a few discussions about Flamenco notations, but so far no
solution I liked.
In this example I created a golpe symbol (needs some enhancements, but I
like it so far) and a rasgueado, which can easily be implemented as an
abanico.

Now what I'ld like is a kinda function that allows me to do something
like:
\rasgueado { <a, e' a cis e>16~ } <a e' a cis e>2 r4^\golpe

My questions:
Is is possible to implement something like that, and if so, where in the
documentation should I start?
(please keep in mind I'm a LilyPond beginner :-S)

Thanks,
Oscar
