# OpenType Feature File specification, section 5.d, example 2.
# http://www.adobe.com/devnet/opentype/afdko/topic_feature_file_syntax.html
# A contiguous set of ligature rules does not need to be ordered in
# any particular way by the font editor; the implementation software
# must do the appropriate sorting.
# So:
feature F1 {
sub f f by f_f;
sub f i by f_i;
sub f f i by f_f_i;
sub o f f i by o_f_f_i;
} F1;
# will produce an identical representation in the font as:
feature F2 {
sub o f f i by o_f_f_i;
sub f f i by f_f_i;
sub f f by f_f;
sub f i by f_i;
} F2;
