Random collection of small tools I needed at the moment
- tiddlytags.rb: Extracts all tags from a tiddlywiki / Bob tiddler directory
- durationcalc.rb: Add / subtract durations (HH:MM)
- qr.rb: Encode the first argument as QR code and display it on the console
Dependencies are managed via bundler. To install everything (locally in this directory) simply run bundle install.
