public class TodoCommentCheck extends AbstractCheck
Checks for TODO: comments. Actually it is a generic pattern matcher on Java comments. To check for other patterns in Java comments, set the format property.

Notes: Using TODO: comments is a great way to keep track of tasks that need to be done. Having them reported by Checkstyle makes it very hard to forget about them.
