# Look up all .mag files in maglef paths from the root
# PDK directory given as the first argument, and replace them with the
# path that is given as the second argument.
# The purpose of this script is to prepare a technology for relocation.
# This script may be expanded to take care of all relocation issues.
# For now, only the property "GDS_FILE" in each .mag file is modified.
# Usage, e.g.:
# /home/tim/pdk/sky130A/libs.ref/sky130_fd_sc_hd/mag /usr/share/pdk/sky130A/libs.ref/sky130_fd_sc_hd/mag
# NOTE: This file is deprecated as moving GDS_FILE properties from
# library to library is taken care of by the open_pdks installer, and
# portability is largely taken care of through use of the $PDK_PATH
# variable in the prefix of the GDS_FILE name.
