I just added support for Elixir to Dependabot!

Each day it will pull down your mix.exs and mix.lock files and check whether the dependencies in them are up-to-date. If there are any that could do with a bump it will create individual PRs for each update for you.

Would love beta testers - Dependabot has created a lot of Ruby and JS pull requests, but support for Elixir is brand new.
