Hey Marc-Andre, what encoding are you using for printing my name? <wink>

Hey Marc-Andre, don't try to reduce /F's crunching efforts to dust.
My argument doesn't hold, but Fredrik has a point and I don't see how
your future changes would invalidate these efforts. If the size of
the distribution can be reduced, it should be reduced! Did you know
that telecom companies measure the quality of their technologies on
a per bit basis? <0.1 wink> Every bit costs money, and that's why
Van Jacobson packet-header compression has been invented and is
massively used. Whole armies of researchers are currently trying to
compensate the irresponsible bloatware that people of the higher
layers are imposing on them <wink>. Careful!
