Detailed Description

Make a system call to return various useful parameters.

This code will make a system call to return various useful parameters. When subroutine summary() is called, a list of system resource statistics is printed to stdout.

Users need to place a call to start() at the beginning of the section of code to be "measured" and a call to summary() at the end.

Use as follows:

call start()
  do stuff
call summary()
