* -g report memory in gigabytes
* -h show this help information
* -k report memory in kilobytes
* -l show long (full) command information
* -m report memory in megabytes
* -o file dump data to json formatted file
* -p proclist specify comma separated list of processes to monitor
* -q run quietly, useful for -o output only
* -s show short command information
* -t top mode, show only changes in memory
* -T top mode, show top memory hoggers
