This rule template can be used to create rules which will be triggered when a comment matches a given regular expression.

For example, one can create a rule with the regular expression ".*WTF.*" to match all comment containing "WTF". Note that, in order to match WTF regardless of the case, the "(?i)" modifier can be prepended to the expression, as in "(?i).*WTF.*".

See Java documentation for detailed regular expression syntax.
