The default page breaking may be overriden by inserting
\pageBreak or \noPageBreak commands. These commands are
analogous to \break and \noBreak. They should be
inserted at a bar line. These commands force and forbid a page-break
from happening. Of course, the \pageBreak command also forces
a line break.
Page breaks are computed by the page-breaking function in the
\paper block.
