You can re-load your entire mod setup on another computer with it, without having to do silly screenshots, or select everything again.
Just make sure you have a backup of the file: "_Aslains_Installer_Options.inf" from the main game folder.
And you've just said what the that program does... it loads the installer, it loads the options file, it starts the installer, with the included options file loaded, so you have everything selected. (You do not need to do this, unless it's a new computer, giving your setup to a friend, or you deleted entire game folder... otherwise installer remembers choices between installations/updates.)
