# Change Log
#
# $Log$
# Revision 1.1 2003-08-31 21:39:52 ahvezda
# Added pads_backannotate perl script
#
# Revision 1.4 2003/07/19 04:34:55 dan
# bring this program up to a usable state. Refdes renumbering is fully
# supported and pin/gate swapping while not supported, gives a report of
# the manual swaps needed.
#
# Revision 1.3 2003/03/03 03:44:26 dan
# Finish up code to handle the RENPART .eco directive. The output files
# are still not written, but everything else is in place to handle backannotation
# of reference designator renumbers.
#
# Revision 1.2 2003/02/21 12:30:30 dan
# fix perl path
#
# Revision 1.1 2003/02/19 23:31:50 dan
# start (non functional so far) of a pads to gschem backannotation tool
#
#
