_RUN_BAS
********

BAS.py starts a server to http://localhost/

---------------------------------- code
#
# Main
#

if __name__ == '__main__':
	BAS(80)
---------------------------------- code

You can change BAS(80) in another port, for example BAS(8080).
Now you can run the program:

python BAS.py


then open http://localhost/ or http://localhost:8080 or other,
with your browser. Appear:

It is OK! Now view the source code...
