+TODO
+----
+
+* detect old grml2usb usage and inform user about it and exit then
+ -> rename grml2usb.py to grml2usb then
+* handling of bootloader configuration for multiple ISOs
+* verify that the specified device is really USB (/dev/usb-sd* -> /sys/devices/*/removable_)
+* validate partition schema? bootable flag
+* implement missing options (--kernel, --initrd, --uninstall,...)
+* improve error handling :)
+* get rid of "if not dry_run" inside code/functions
+* implement mount handling
+* implement logic for storing information about copied files
+ -> register every single file?
+* trap handling (like unmount devices when interrupting?)
+* get rid of all TODOs in code :)
+* graphical version? :)
