FontLab 4

A contiguous set of ligature rules does not need to be ordered in any
particular way by the font editor; the implementation software does the
appropriate sorting. So:
sub f f by ff;
sub f i by fi;
sub f f i by ffi;
sub o f f i by offi;
will do the same thing as:
sub o f f i by offi;
sub f f i by ffi;
sub f f by ff;
sub f i by fi;
