+//nxadm/tail provides a Go library that emulates the features of the BSD `tail`
+//program. The library comes with full support for truncation/move detection as
+//it is designed to work with log rotation tools. The library works on all
+//operating systems supported by Go, including POSIX systems like Linux and
+//*BSD, and MS Windows. Go 1.9 is the oldest compiler release supported.
