-LilyPond contains special definitions for music for the Scottish
-highland bagpipe; to use them, add
-
-@example
-\include "bagpipe.ly"
-@end example
-
-@noindent
-at the top of your input file.  This lets you add the special gracenotes
-common to bagpipe music with short commands.  For example, you could
-write @code{\taor} instead of
-
-@example
-\grace @{ \small G32[ d G e] @}
-@end example
-
-@code{bagpipe.ly} also contains pitch definitions for the bagpipe
-notes in the appropriate octaves, so you do not need to worry about
-@code{\relative} or @code{\transpose}.

-Bagpipe music nominally uses the key of D Major (even though that
-isn't really true).  However, since that is the only key that can be used,
-the key signature is normally not written out.  To set this up correctly,
-always start your music with @code{\hideKeySignature}.  If you for some
-reason want to show the key signature, you can use @code{\showKeySignature}
-instead.
-
-Some modern music use cross fingering on c and f to flatten those notes.
-This can be indicated by @code{cflat} or @code{fflat}.  Similarly, the
-piobaireachd high g can be written @code{gflat} when it occurs in light
-music.
