A fix me is a CodeBadge in code (or a WikiBadge in a wiki) that can be used to indicate where something is flawed or merely a stub in place of a real implementation. If you know how to fix it, replace the FixMe with a fix. A FixMe differs from a CodeSmell in that the author of a FixMe is 100% confident they know hoe to fix it. See also: CodeSmell
A good FixMe gives a thorough description of how to fix the problem. For example, a good code FixMe would be:
# FIXME: Remove this function from the published interface; it is wholly private to this module.
