+     "The 'time' command runs another program, then displays information
+about the resources used by that program, collected by the system while
+the program was running.  You can select which information is reported
+and the format in which it is shown, or have 'time' save the information
+in a file instead of displaying it on the screen.
+
+The resources that 'time' can report on fall into the general categories
+of time, memory, and I/O and IPC calls.  Some systems do not provide
+much information about program resource use; 'time' reports unavailable
+information as zero values.
