Sized Contents

[Thomas J. Webb]

I have a question. I'm new to LilyPond, so feel free to laugh histerically at 
this question's naivete:

I'm trying to create sheets that are *automatically* sized just to fit the 
contents, so it's meant for web-viewing, not print. Does anyone have any ideas? 
I've been hunting through the manual to no avail. I know I can do trial and 
error to get the right size, but that's not what I'm after. I want to be able 
to automatically (say, from a script) generate images of notes, rather than 
full sheet music. Is there any way to know the height of the contents without 
digging into LilyPond's code?
