Log rotation

Tail comes with full support for truncation/move detection as it is designed to work with log rotation tools.

Installing

go get github.com/hpcloud/tail/...

Windows support

windows should use poll mode instead of fsnotify

tail.TailFile("/var/log/nginx.log", tail.Config{Follow: true, Poll: true})

This package needs assistance for full Windows support.
