For those Tux Racer users living in the United States,
here's a patch to make a minor cosmetic change to the
HUD display. Instead of speeds in kilometers per hour,
it will now show the speed in miles per hour.
Just copy the patch into the src subdir of your Tux
Racer source directory, and run:
patch -p0 < mph.patch
(I'm not sure if you need to be root on Linux).
This works under Linux, and it should work under other
OSes (it's not as if they matter)... 8-)
