I searched the tree and apparently there is no documentation
whatsoever on what ioctlent.sh is and how to use it.
I assume it is used to refresh ioctldefs.h from time to time.
However, I only _assume_, and you apparently actually used it recently.
Can you write up a little explanation/HOWTO about it?
I intend to add it to the cvs.
I also will use it to validate future patches for ioctlent.sh.
