Me too. I've been here before, I was one of about 8 people who actually
knew that AT&T should have won the BSD lawsuit because I diffed the code.
And you can't diff it with a perl script, that simply doesn't work. The
only real ways that I know of are
a) have a human do it, function by function
b) compile the code to an expression tree and then diff the expression
trees.
