/* prio.c - prio command for BeOs, change priority of a given thread
 * (c) 2001, 2002, François Revol (mmu_man) for OpenBeOS
 * released under the MIT licence.
 *
 * ChangeLog:
 * 04-26-2002 v1.2
 *  fixed a typo on error (Priority changed failed.)
 * 04-25-2002 v1.1
 *  Initial. Used my renice.c code to rewrite 'prio' BeOS command for OpenBeOS.
 * 
 * prio is a stripped-down version of renice
 * seems to behave the same way as the original BeOS version. :)
