# 
# Supported on Unix/Mac/Windows with Python 3

# #########
# Execution
# #########
# This program is written for Python 3.
# Please make sure you are running this program with Python 3, NOT Python 2.
# 'python' from your terminal needs to link to Python 3, NOT Python 2.
# 
# For execution from a terminal, you may try:
# 
# Unix/Mac/Windows:
# -----------------
# python3 configure_secnet.py3
# python configure_secnet.py3
#
# Unix/Mac:
# ---------
# /usr/bin/python BetaTurnTool18.py2
# /usr/bin/python2 BetaTurnTool18.py2
# /usr/bin/env python BetaTurnTool18.py2
# /usr/bin/env python2 BetaTurnTool18.py2
#
# For Shebang (Hashbang) in Unix/Mac:
# -----------------------------------
# Make sure in the top line 'python3' links to Python 3
# If Python 3 is not linked with python3 but with python, please modify the top line to "#!/usr/bin/env python"
#
# Windows:
# --------
# C:\Python3\python3.exe configure_secnet.py3
