+most beautifully typeset piece of music in our collection of music (we
+both own one. It is also lovely on French Horn). This piece does not
+include articulation, but it does follows the same beaming and
+linebreaking as the printed edition. This is done in order to
+benchmark the quality of the LilyPond output.
+
+As of lilypond 1.5.42, the spacing and beam quanting is almost
+identical.
+
+There are two tweaks in this file: a line-break was forced before
+measure 25, we get back the linebreaking of Bärenreiter. The stem
+direction is forced in measure 24. The last beam of that measure is up
+in Bärenreiter because of context. We don't detect that yet.
+
+Note that the Bärenreiter edition contains a few engraving
+mistakes. The second line begins with measure 6 (but prints 5). The |:
+half way in measure 13 has been forgotten.
