auto-beam

[David Bobroff]

I'm trying to set auto-beams.  I have a piece with:

\time 2/2

By default, LilyPond wants to beam across two quarter notes worth of beamed
notes.  This is fine as long as it is only eighth notes.  I don't want to
have two eighths + four sixteenths beamed together, nor do I want eight
sixteenths beamed together.

The rule I would like to define could be stated as follows:

A beam may not be more than a quarter note in length if sixteenth notes are
contained in it.

Is it possible to do this?  I've been looking at:

omatic-beam-behavior.html#Setting-automatic-beam-behavior

...and have not yet figured out how to do this.
