Sick and tired of sketching on paper the calculations to take a length of frame material and account for matting to make a frame, thought I'd Make (my) Life Easier™.

• Sinatra to React.js
• Coffeescript to Ecmascript
• History / Auto load
• Colour picker for frame/matt
• Optional increase of number of matts
• Non-uniform matting

Docker is sweet.

docker-compose -f docker-compose.dev.yml build web

docker-compose -f docker-compose.dev.yml run web

With Docker you'll need to do the old double install trick:

1. Install into existing container to update the Gemfile.lock file; and
2. Rebuild your container using the updated Gemfile.lock.
