 The parser (parser.go) is a partial implementation of this state machine (http://vt100.net/emu/vt500_parser.png).  There are also two event handler implementations, one for tests (test_event_handler.go) to validate that the expected events are being produced and called, the other is a Windows implementation (winterm/win_event_handler.go).
 
 See parser_test.go for examples exercising the state machine and generating appropriate function calls.

-
-## Usage
-
-```go
-import (
-  "log/syslog"
-  "github.com/Sirupsen/logrus"
-  logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
-)
-
-func main() {

-
-  if err == nil {
-    log.Hooks.Add(hook)
-  }
-}
-```
-
-If you want to connect to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). Just assign empty string to the first two parameters of `NewSyslogHook`. It should look like the following.
-
-```go
-import (

-  logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"

-func main() {

-  hook, err := logrus_syslog.NewSyslogHook("", "", syslog.LOG_INFO, "")
