# Script to load SWiG environment.
# This script sets all the paths to the SWiG and its submodule executables.

# To use this script, source it in your BASH terminal with:
#   . load_swig_env.sh

# You should then have all executables and scripts in your path,
# allowing you to run SWiG.
# Note - this assumes you have followed the instructions in each submodule
#        to build/compile each submodule.
