+
+The @code{ly:one-line-auto-height-breaking} function works just like
+@code{ly:one-line-breaking} except the page height is automatically
+modified to fit the height of the music. Specifically, the
+@code{paper-height} variable in the @code{\paper} block is set so that
+it spans the height of the tallest score plus the @code{top-margin} and
+@code{bottom-margin}.
+
+Note that the @code{top-system-spacing} setting will affect the
+vertical position of the music. Set it to @code{##f} in a paper block
+to simply place the music between the top and bottom margins.
