 # cpulimit
 
+cpulimit is a simple program which attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time).
+This is useful to control batch jobs, when you don't want them to eat too much cpu.
+It does not act on the nice value or other scheduling priority stuff, but on the real cpu usage.
+Also, it is able to adapt itself to the overall system load, dynamically and quickly.
