Description:
Run this ULP in your board layout and it will generate a script file that regenerates the board from scratch. This may be useful if you need to make significant library changes or if you need to switch between versions, for example.  It is important to run the ULP right after opening the board file.  If you do a ratsnest before running the ULP, the polygons will switch from Outline mode to Real mode and they will export as a complicated shape rather than the outline.  Also, because of rounding errors many small Airwires may appear in the new board file.  These can be deleted in bulk without consequence.
