+# This script is intended to be used on RR graph XML files generated by VPR.
+# If the architecture is a 2D architecture, you can simply call this script
+# to remove all attributes related to 3D FPGA support (layer="0",
+# layer_low="0", layer_high="0"). In VPR, these values default to 0.
+
+# This also helps convert older RR graph files that used the "layer" attribute
+# instead of "layer_low" and "layer_high" for nodes, by removing the "layer" attribute
+# altogether. As a result, VPR can read the file without issues, and it slightly
+# reduces the file size for 2D architectures.
+
+# Exit if any command fails
