-@node Avoiding tweaks with slower processing
-@subsection Avoiding tweaks with slower processing
-
-LilyPond can perform extra checks while it processes input files.
-These checks will take extra time to perform, but fewer manual tweaks
-may be required to obtain an acceptable result. If a text script
-or part of the lyrics extends over the margins these checks will
-compress that line of the score just enough to fit within the
-margins.
-
-To be effective under all circumstances these checks must be enabled
-by placing the overrides in a Score @code{\with} block, rather than
-in-line in music, as follows:
-
-@example
-\new Score \with @{
- % Makes sure text scripts and lyrics are within the paper margins
- \override PaperColumn #'keep-inside-line = ##t
- \override NonMusicalPaperColumn #'keep-inside-line = ##t
-@} @{
- ..
-@}
-@end example
-
-However, @code{keep-inside-line} is expensive and the recommendation
-is to not enable it, to allow for faster processing, until creating
-a final version. This way you do not need to manually add @code{\break}
-commands to avoid text running off the right-hand side of the page.
