+# Tail implementation in Go
+
+A Go package striving to emulate the BSD `tail` program. 
+
+```Go
+t := tail.TailFile("/var/log/nginx.log", 1000, true, true)
+for line := range t.Lines {
+    fmt.Println(line.Text)
+}
+```
+
+## TODO
+
+* tests
+* command line program (`tail -f ...`)
+* refactor: use Config? `NewTail(tail.Config{Filename: "", Follow: tail.FOLLOW_NAME})`
+* refactor: get rid of 'end' flag; allow `-n <number>` with `-n -1`
+  for end.
