Usually, when we get replacements, they are.

Which it isn't unless they are truly correct in their assumptions of
output behavior.

Not _necessarily_, but realistically...

That's true. I'd like to see the replacement grep do mmaping of the
input files if it doesn't already, as that would speed it up. Anyway,
I haven't tried it out yet because I haven't seen it hit 1.0 :) The
only good pre-1.0 software I've seen has been the GIMP, XRacer, and
some little utilities (like a program called stat(1)).
That reminds me. I'd like to see something like stat(1) go into the source
tree, but only if it were freely licensed, not GPL-infected. I could do
it in a day, I suppose, if it were worth it. Worth it is here defined as
"would be accepted to go in usr.bin."
