How do I avoid printing any grace notes?

[Sven Axelsson]

I know, I should be able to figure this out by reading the
documentation, but I'm lazy ...

Is there a simple way of telling Lilypond to omit all grace notes from
a piece? I want
to use it to print bagpipe music (which uses lots and lots of grace
notes) in such a
way that it can be played by concert pitch instruments. I want to be
able to call a single
command that does this, so I can use the same score for bagpipe as for
other instruments.

Ideally I should be able to do e.g.:

\transpose a bflat
{
    \bagpipeKey
    \showTrueKeySignature
    \removeGracenotes

    % Music here
}

I guess the \removeGracenotes command would do something to the effect of

\override Grace_engraver = Harakiri_engraver

but differently, and with different syntax, obviously.

Thanks much.
