+The header and footer are created by the functions make-footer and
+make-header, defined in \paper. The default implementations are in
+ly/paper-defaults.ly and ly/titling-init.ly.
+
+The page layout itself is done by two functions in the \paper block,
+page-music-height and page-make-stencil. The former tells the
+line-breaking algorithm how much space can be spent on a page, the
+latter creates the actual page given the system to put on it.

+You can define paper block values in Scheme. In that case mm, in, pt,

 You can also define these values in Scheme.  In that case @code{mm},
