+ * shadowJar when Getdown is not used or available. It attempts to take all the
+ * command line arguments to pass on to the jalview.bin.Jalview class, but to
+ * insert a -Xmx memory setting to a sensible default, using the -jvmmempc and
+ * -jvmmemmax application arguments if specified. If not specified then system
+ * properties will be looked for by jalview.bin.MemorySetting. If the user has
+ * provided the JVM with a -Xmx setting directly and not set -jvmmempc or
+ * -jvmmemmax then this setting will be used and system properties ignored. If
+ * -Xmx is set as well as -jvmmempc or -jvmmemmax as argument(s) then the -Xmx
+ * argument will NOT be passed on to the main application launch.
