+# Graylog
+This library provides support for sending GELF formatted messages to Graylog.
+Currently the UDP chunked method is the only method supported.
+
+```haskell
+import Graylog.UDP
+
+main :: IO ()
+main = do
+   eglog <- openGraylog "192.168.99.100" "12201" defaultChunkSize
+   case eglog of
+      Left  e -> assertFailure e
+      Right g -> sendLog g sample >> closeGraylog g
+   where
+      sample = simpleGelf "localhost" "hello world!"
+```
