# commentcode.py
#
# Checks : Commented-out code.
#
# Reason : Instances of code that are commented out make the code
# hard to maintain and to interpret clearly. The commented out code
# should be removed. Any requirement to rediscover old code
# should be made through source control and not by trawling through
# commented-out code.
