USAGE: $0 [--options]

Image options:
	-i|--interactive        interactive mode with image selection

                                vm lists only VMware images, use only w/ xdm
        -s|--start <image-name>	start image /\${vmdir}/<image-name>.vmdk
	-a|--alias		use aliases
	--silent		no stdout from runvmware
        --mem <n(M(h))|n(G(h))>	override autoallocation of memory, in percent
                                m,M megabyte, g,G gigabyte, h,H reserve f. host
        --res <X_intxY_int>     Maximum resolution of the guest os, e.g. 800x600
	--delay <n seconds>	delay the start of the script n seconds
	--image <directory>	specify image directory
	--persistent		use persistent mode
	--vmostype <vmwareos>   define VMware ostype
        --include <includefile> include code right before program start
	--displayaliases	aliases you can use with option -a
        --floppya               enable floppy disk
        --floppyb               use /etc/vmware/fd-loop as floppy B,
                                needed for exchanging files w/ VMware
VMware options:
        --run <program>         specify programm, e.g. vmware, vmplayer, ...
	--windowed		start in windowed mode
	--edit			only open config file in vmware (only VMware)
