# Checks : Assignment in an If statement.
#
# Reason : Assignments inside an If statement often indicate that 
# the assignment was not intended. Even if the assignment was 
# intended, it is clearer to separate out the assignment from the 
# conditional. The script that detects such occurrences has a few 
# false positives when the action statements are on the same line 
# as the conditional check. However, this is also against the 
# coding standards and the action should be on a separate line.
