memory.size

All,
In the help for memory.size, there is:

Details:

     Command-line flag '--max-mem-size' sets the maximum value of
     obtainable memory (including a very small amount of housekeeping
     overhead).

How does one implement a command-line flag in order to set the max for memory?

cheers,
dave
