Hello,
I've attached an example of an eventual installer/restorer for DR800+.
Note that although the script expects zenity binary to be included with the package to install, that wouldn't be possible in real world because zenity needs libglade and libgnomecanvas libraries and some helper files in $PREFIX/share.
libglade is used in scale, calendar, file_selection and entry widgets, so it's not easily dropped from zenity in order to compile a zenity light version.
It's a pity because we would get an GUI helper for only 66 KB... Anyway, require people install "_base" package and problem solved

.
