    19 # Checks : Commented-out code.
       
    20 #
       
    21 # Reason : Instances of code that are commented out make the code 
       
    22 # hard to maintain and to interpret clearly. The commented out code 
       
    23 # should be removed. Any requirement to rediscover old code 
       
    24 # should be made through source control and not by trawling through 
       
    25 # commented-out code.
