; This is a little gimp script for creating the image
; headers. You need to edit the last five lines of this
; file to suit your needs. Need to add the image flatten,
; index, and save as gif. Right now you have to do that
; manually. Hopefully I can write something in java that
; produce an image that looks as good as this one. For
; now it's scheme ... Yuck!

; move this to your /usr/share/gimp/scripts directory
; or the equivalent on your machine.
