-# File system notifications for Go
-
-[](http://godoc.org/github.com/howeyc/fsnotify)
-
-Cross platform: Windows, Linux, BSD and OS X.
-
-## Moving Notice
-
-There is a fork being actively developed with a new API in preparation for the Go Standard Library:
-[github.com/go-fsnotify/fsnotify](https://github.com/go-fsnotify/fsnotify)
-
-## Example:
-
-```go
-package main
-
-import (
- "log"
-
- "github.com/howeyc/fsnotify"
-)
-
-func main() {
- watcher, err := fsnotify.NewWatcher()
- if err != nil {
- log.Fatal(err)
- }
-
- done := make(chan bool)
-
- // 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("testDir")
- if err != nil {
- log.Fatal(err)
- }
-
- <-done
-
- /* ... do stuff ... */
- watcher.Close()
-}
-```
-
-For each event:
-* Name
-* IsCreate()
-* IsDelete()
-* IsModify()
-* IsRename()
-
-## FAQ
-
-**When a file is moved 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 (a recursive watcher is in the works [#56][]).
-
-**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 (see [#7][])
-
-**Why am I receiving multiple events for the same file on OS X?**
-
-Spotlight indexing on OS X can result in multiple events (see [#62][]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#54][]).
-
-**How many files can be watched at once?**
-
-There are OS-specific limits as to how many watches can be created:
-* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit,
-reaching this limit results in a "no space left on device" error.
-* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.
