Simplest way to get notes without staves

[John Allsup]

Hi,

I am new to lilypond and want (so as to have a graphic), a pair of 
quavers and a quadruple of
semiquavers just on their own (i.e. no staff or time signature.)  What 
is the easiest way to do this
in Lilypond.  (I am aware I could probably find some method, but I have 
a habit of finding ugly
hacks when I do this with an unfamiliar system.)

Cheers,

John
