/*
 * If you enjoyed the functionality of my 1994 IOCCC entry (you like having
 * a clock on your screen at all times) but you do not want to use up 7 
 * process slots to run the code, then this is the program for you. This
 * program uses ANSI/VTxxx escape sequences and perodic time(3) calls to 
 * print a clock in the upper right corner of you screen.
