-  Plug to set the locale based on the Accept-Language header.
-
-  ## Usage
-
-  Add the plug to your pipeline in `router.ex`:
-
-      pipeline :browser do
-        ...
-        plug ClaperWeb.Plugs.Locale
-      end
-
-  ## Configuration
-
-  The plug will use the `:default_locale` configuration value as the default
-  locale. If the `:default_locale` is not set, it will default to `:en`.
-
-  ## Accept-Language header
-
-  The plug will parse the `Accept-Language` header and set the locale to the
-  first language in the list that is known to the application. If no language
-  is known, the locale will not be changed.
-
-  The `Accept-Language` header is a comma-separated list of language tags with
-  optional quality values. The quality value is a number between 0 and 1,
-  where 1 is the highest quality. The quality value is optional and defaults
-  to 1.
-
-  Examples:
-
-      Accept-Language: en-US,en;q=0.8,da;q=0.6
-
-  The above example will set the locale to `:en` if it is known to the
-  application. If `:en` is not known, it will set the locale to `:da` if it is
-  known to the application. If neither `:en` nor `:da` is known, the locale
-  will not be changed.
-
-      Accept-Language: en-US,en;q=0.8
-
-  The above example will set the locale to `:en` if it is known to the
-  application. If `:en` is not known, the locale will not be changed.
-
-      Accept-Language: en-US
-
-  The above example will set the locale to `:en` if it is known to the
-  application. If `:en` is not known, the locale will not be changed.
-
-  ## Known locales
-
-  The plug will only set the locale if it is known to the application. The
-  known locales are determined by the `:gettext` configuration. The
-  `:gettext` configuration is set in `config/config.exs`:
-
-      config :claper, ClaperWeb.Gettext,
-        default_locale: "en",
-        default_domain: "claper",
-        available_locales: ~w(en fr)
