I want to remove the all references in the .fzp file to the old part it was created from, ie the "sparkfun-connectors-50-pin-centronics-m-male,fzp", so the part is indistinguishable from a new part.

Do I need the line, or can I change it to something referencing the part it's self, or do I have to edit the file and create a new file, and will it work for others that don't have the file when they import the part.
