Todidnt is a command line utility to help you track down TODOs and FIXMEs that you always said you'd do but haven't actually done yet. It also generates pages (rdoc-style) to show you things like pretty graphs of your repository TODOs over time.
Install the gem:
gem install todidnt
todidnt in any Git repository directory:
Paul Battley (@threedaymonk) for initial idea and witty name.
