    (description
     "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.")
