# Please note that config files are Python source code!
# A common mistake is to put an option list (such as TemplateChecks,
# JSONRPCAddresses, etc) excluding the final comma.
# For example (this is WRONG):
#     JSONRPCAddresses = (
#         ('', 8337)  # <-- there must be a comma after EVERY item, even last
#     )
# Without the final comma, should the option list ever have only one item in
# it, Python would interpret the "main" parenthesis as a mere sub-expression
# instead of a list of values. If that occurs, you might get crazy errors, or
# things might just not work correctly. Be careful to not miss the commas.
