If set to true (which it is by default in this patch) it gives you a new button on the start battle scape dialogue giving you the option to auto-win. This will let you pick up points and salvage from the mission, and a coach load of alive and surprised aliens all ready for water-boarding.
I figured this would be useful for Geoscape testing prior to the battlescape being finished.

edit: forgot a file in the patch. Autowin2 is good.
