Image options:
-i|--interactive interactive mode with image selection
-o|--os <ostype> start ostype, e.g. winxp, suse,...
(first part of image name (winxp-pro.vmdk))
-s|--spec <spec.> specify your image, e.g. pro, home,...
(second part of image name (winxp-home.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
--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
--floppyb use /media/loop0 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)
--donotquit do not quit after image stopped (only VMware)
runvmware options:
-h|--help this help
--version
--debug <level> level 1 -> print stdout to file
