Usage: 
    #{File.basename($0)} list          prints all available emulators
    #{File.basename($0)} running       shows all running emulators
    #{File.basename($0)} kill          kills all running emulators
    #{File.basename($0)} launch ID     runs the emulator with ID,
                                       ID is an integer form the output of `list`
    #{File.basename($0)} targets       shows all possible targets and skins, will only display targets with abi
    #{File.basename($0)} new ID SKIN   creates a new avd with API level according to ID and skin SKIN
                                       check `targets` for possible values (depends on installed sdk packages)
                                       Only works for targets with default abi
    #{File.basename($0)} rm ID         deletes avd with ID returned in list"
