36    * command line arguments to pass on to the jalview.bin.Jalview class, but to
37    * insert a -Xmx memory setting to a sensible default, using the --jvmmempc and
38    * -jvmmemmax application arguments if specified. If not specified then system
39    * properties will be looked for by jalview.bin.MemorySetting. If the user has
40    * provided the JVM with a -Xmx setting directly and not set --jvmmempc or
41    * --jvmmemmax then this setting will be used and system properties ignored. If
42    * -Xmx is set as well as --jvmmempc or --jvmmemmax as argument(s) then the -Xmx
43    * argument will NOT be passed on to the main application launch.
