 # This file is responsible for configuring your application
 # and its dependencies with the aid of the Mix.Config module.
 use Mix.Config
 
 # This configuration is loaded before any dependency and is restricted
 # to this project. If another project depends on this project, this
 # file won't be loaded nor affect the parent project. For this reason,
 # if you want to provide default values for your application for
 # 3rd-party users, it should be done in your "mix.exs" file.
 
 # You can configure for your application as:
 #
 #     config :kolab_wopi, key: :value
 #
 # And access this configuration in your application as:
 #
 #     Application.get_env(:kolab_wopi, :key)
 #
 # Or configure a 3rd-party app:
 #
 #     config :logger, level: :info
 #
 
 # It is also possible to import configuration files, relative to this
 # directory. For example, you can emulate configuration per environment
 # by uncommenting the line below and defining dev.exs, test.exs and such.
 # Configuration from the imported file will override the ones defined
 # here (which is why it is important to import them last).
 #
 #     import_config "#{Mix.env}.exs"
