# Usage
#
#  klayout -rd input=in.def -rd map=in.map -rd lefs=in.lef,in_tech.lef -rm path_to_script/import_def.rb
#
# Variables (-rd <name>=<value):
#  input:  path to DEF file
#  map:    path to map file
#  lefs:   comma-separated list of LEF files (relative to DEF file location)
#
# Optional:
#  lef_macros: (without value) if given, LEF macro geometries will be read into DEF  
#  macros:     A comma-separated list of other layout files to read for substituting LEF macros
