Schedtool interfaces with the Linux CPU scheduler.

It allows the user to set and query the CPU-affinity and nice-levels of 
processes, as well as all scheduling policies, like batch or real-time 
(RR/FIFO) classes and their priorities.  It can be used to avoid skipping 
for A/V-applications, to lock processes onto certain CPUs on SMP/NUMA 
systems, or to adjust nice-levels of lesser important jobs to maintain a 
high amount of interactive responsiveness under high load.

All special scheduling classes of the -ck kernel patchset are also supported.

Certain modes (as of this writing: SCHED_IDLEPRIO and SCHED_ISO) need a
patched kernel; see the INSTALL file for details.
