Mainly to support other features we've added bash functions which we thought we might as well turn into command line options. No, we didn't do this in order to compete on number of command line options - we know that gcc will probably beat us ten times over. Anyhow, here are the new command line options:
--unlock-screen - Unlocks the screen, only supported on Android
--print-client-settings - For a given client the settings are printed to stdout
--get-client-os - For a given running client
Oh yes, one more thing. When using a visible VirtualBox (as opposed to headless) vmm tries to maximise your vbox window usng wmctrl. In case wmctrl is not present vmm warns and continues. Before there were a lot of garbage printed out from bash - now it is more controlled.
