+
+If using any combination of @code{\header@{@}}, @code{\score@{@}} or
+@code{\layout@{@}} in your example, then you must omit the
+@code{relative} variable and either use absolute entry mode or an
+explicit @code{\relative@{@}} construction.
+
+If using @code{\book@{@}} in your example then you must also omit the
+@code{relative} variable and either use absolute entry mode or an
+explicit @code{\relative@{@}} construction. However, you must also
+include the @code{papersize=X} variable, where @code{X} is a defined
+paper size from within @file{scm/paper.scm}. This is to avoid the
+default @code{a4} paper size being used and leaving too much unnecessary
+whitespace and potentially awkward page breaks in the PDFs.
+
+The preferred @code{papersize}s are @code{a5}, @code{a6} or
+@code{a8landscape}.
+
+@code{a8landscape} works best for a single measure with a single title
+and/or single @code{tagline}:

+
+and can also be used to easily show features that require page breaks
+(i.e. page numbers) without taking large amounts of space within the
+documentation. Do not use the @code{quote} option with this paper size.
+
+@code{a5} or @code{a6} paper sizes are best used for examples that have
+more than two measures of music or require multiple staves (i.e. to
+illustrate cross-staff features, RH and LH parts etc.) and where
+@code{\book@{@}} constructions are required or where @code{a8landscape}
