This package provides a way to insert fixme notes in documents being developed (in draft mode). Such notes can appear in the margin of the document, as index entries, in the log file and as warnings on stdout. It is also possible to summarize them in a list. If your document is in a final version, any remaining fixme notes will produce an error. FiXme also comes with support for AUC-TeX. The author is Didier Verna.
