-
-The global paper layout is determined by three factors: 
-the page layout, the line breaks, and the spacing. These all 
-influence each other. The choice of spacing determines how 
-densely each system of music is set. This influences where line 
-breaks are chosen, and thus ultimately, how many pages a piece 
-of music takes.
-
-Settings which influence layout may be placed in two blocks.
-The @code{\paper @{...@}} block is placed outside any
-@code{\score @{...@}} blocks and contains settings that
