The fast-tags package

[Tags:bsd3, library, program, test]

Yet another tags program. Like hasktags, it uses its own parser rather than haskell-src or haskell-src-exts, so it's fast. It understands hsc and literate haskell.

In addition, it will load an existing tags file and merge generated tags.

The intent is to bind it to vim's BufWrite autocommand to automatically keep the tags file up to date. This only works for files changed by the editor of course, so you may want to bind 'rm tags' to a pull posthook.
