How to tell how much of the page has been printed on?

[Ed Stauff]

Is there a way to determine how much of the page LilyPond has printed 
on?  I want to generate music notation images for use on a website, but 
I don't want to waste a whole 8"x10" area if there's only one or two 
lines of music.  Examining the LilyPond output by eye and trimming it by 
hand is out of the question; I have several thousand pieces of music to 
process.  What I mainly need to know is the page height used; the width 
isn't as important.

Thanks,

-- Ed
