Cross platform, works on:

• Windows
• Linux
• BSD
• OSX

Example:

    watcher, err := fsnotify.NewWatcher()
    if err != nil {
        log.Fatal(err)
    }

    // Process events
    go func() {
        for {
            select {
            case ev := <-watcher.Event:
                log.Println("event:", ev)
            case err := <-watcher.Error:
                log.Println("error:", err)
            }
        }
    }()

    err = watcher.Watch("/tmp")
    if err != nil {
        log.Fatal(err)
    }

    /* ... do stuff ... */
    watcher.Close()

For each event:

• Name
• IsCreate()
• IsDelete()
• IsModify()
• IsRename()

Notes:

• When a file is renamed to another directory is it still being watched?
  • No (it shouldn't be, unless you are watching where it was moved to).
• When I watch a directory, are all subdirectories watched as well?
  • No, you must add watches for any directory you want to watch.
• Do I have to watch the Error and Event channels in a separate goroutine?
  • As of now, yes. Looking into making this single-thread friendly.
