Re: display chords (Ami7(b5))

[David Stocker]

Thanks Shamus, this is great.

Incidentally, if you store a copy of "pop-chords.ly" in your lilypond's 
usr/share/lilypond/current/ly folder (or somewhere else in LilyPond's 
path) you can call it using \include just like the language-settings 
files (i.e. without having to put a copy of it in your current working 
directory).

I will get much use from this.
