Usage: $0 [--what=key] [--help] [--pretty]
* --what : if a key is given (eg --what=Bytes_received) will print only this value.
Else, all the stats are printed in a json format.
Run once without --what to get a list of available keys
* --help : print this help and exit
* --defaults : set the file from which mysql will read defaults
* --host : set the hostname to connect to
* --user : set the user to connect as
* --password : set the password to use
* --pretty : prints JSON in a pretty, human readable format. Has no use when --what is also given
