best solution for book making with multiple scores and multiple titles but w/o page breaks between pieces

[Mike Solomon]

Hey all!

\bookpart forces a page break between pieces in a suite, which I don’t want, 
but otherwise I like how it prints robust titles for each work.
Is there a way to do everything that \bookpart does minus the page breaks?  I 
can create top-level markups instead of using the \header, but it’d be less 
work to just use the \header.

Cheers,
