Chord lookup table in lily 1.2.17

[Amelie Zapf]

Dear Lilypond folks,

now that I'm back into the 1.2 versions of lily (because of bar repeats), could
someone please tell me in what file the chord lookup table (meaning the table
that gives names to chords given in intervals) is in this distribution, as I
might want to change it to suit my "jazzy" needs. (Of course that would be
easier in the 1.3 versions, but I need the bar repeat).

Anyone can remember?
Thanks to y'all,

Amy
