I'm using Lilypond intensively for a few months and I'm extremely happy with it. Nevertheless I've a suggestion for the empty page template from ยง 8.5.2.
Since I notate pianomusic with 2 or more staves, it's rather practical to remove the clef and set the indentation to zero. Here it is as I use it. It's only a slight modification. Excuse me for the bad indentation, but this is not copied well into my e-mail.
Merry Christmas,
Martijn
\paper { indent = #0 }
emptymusic = { \repeat unfold 2 % Change this for more lines { s1\break } \bar "" }
