I have no idea what the differences in lines between Fruit and Toga is but i
would guess it's a bit more than 50 lines.
One could count the initialization of a table as one line, because it can be
written in one line or 100 lines which only changes readability of the source
code, but not the executable itself.
Another possibility would be to count the actual modifications (not the lines)
which might give a more acurate picture, because one could add a table of 1000
lines to Fruit that does nothing and claim he changed 1000 lines but it would
be only one unimoprtant modification.
