tag-not-ed is a system that allows you to create and manage text documents by attaching tags to them. Later, documents can be retrieved by running queries on those tags (e.g., "show me all docs that deal with 'dogs' and 'cats'"). It is composed of a front-end (currently a mode for the jed text editor) and an indexer. The latter can be used to implement a rudimentary "tagging file system".
