+# EventSourceEncoder
+
+EventSourceEncoder is a Elixir library to encode data into EventSource
+compliant data.
+
+## Examples
+
+``` elixir
+iex> EventSourceEncoder.encode(1, "This is data")
+"id:1\\ndata: This is data\\n\\n"
+
+iex> EventSourceEncoder.encode(1, "This is new data", :login)
+"id:1\\nevent:login\\ndata: This is new data\\n\\n"
+```

+
+# Note this file is loaded before any dependency and is restricted

+# Sample configuration:
+#
+#     config :my_dep,
+#       key: :value,
+#       limit: 42
+
+# It is also possible to import configuration files, relative to this

+# 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).
