# the purpose of this script is rewriting the swig_import_helper
# call so it will not load _xxxxx.so/dso from inside a kicad executable
# because the kicad executable itself sill provide an _xxxxx module
# that's linked inside itself.
#
# for the normal module import it should work the same way with this
# fix in the swig_import_helper
