package filenotify

import "github.com/docker/cli/components/engine/pkg/filenotify"

Package filenotify provides a mechanism for watching file(s) for changes. Generally leans on fsnotify, but provides a poll-based notifier which fsnotify does not support. These are wrapped up in a common interface so that either can be used interchangeably in your code.
