"""
Usage: sar.py -o <option> -p <prefix> -s <starttime> -e <endtime> -d

Args:

-d - Run in debug mode
-e - End time on the graph
-h - Help. Print this syntax message.
-p <prefix> - Specify file prefix
-o <option> - Specify a sar function, such u, g, p, ...
The default is u (CPU).
-s - Start time on the graph
-v - Run in verbose mode

Examples:

'sar.py -ou -i20030705' Process 20030705.sadc
