+/* machine.c, 27-03-1990, F. Meulenbroeks
+ * usage: machine [machine name]
+ *        chip [chip name]
+ * where machine name or chip name are the same as the macros from 
+ * <minix/config.h>
+ * 
+ * When executed without arguments this program returns either the machine name
+ * or the chip name as found in <minix/config.h>
+ * the chip name is returned if argv[0] ends on "chip". 
+ * otherwise the machine name is returned
+ *
+ * when executed with an argument that argument is (case insensitive)
+ * compared with the machine name, and depending on whether these match
+ * or not 0 or 1 is returned as the exit code. In this case nothing is printed
