/* DESCRIPTION */
/* The purpose of this "reboot" program is to send a TCP message to another
 * computer that has specially made hardware attached to it that will reboot
 * another computer -- in our case, a vxWorks PowerPC computer.
 *
 * To compile this program, type something like the following:
 * gcc -O2 -lsocket -lnsl reboot.cpp -o reboot
