2 questions

[Bec and John]

Hi,

I have 2 questions about Lilypond usage:

1) Using the \book option and using the piece property to name each  
\score, how can I centre the piece name instead of having small text  
all the way over to the left?

2) There isn't enough room between consecutive pieces, how can I  
increase the amount of space between pieces? The answer to question 1  
would actually negate this question, but it'd be nice to know anyway.

Thanks!
