-# resync
-
-`sync.Once` with `Reset()`
-
-  * See [sync.Once](http://golang.org/pkg/sync/#Once)
-
-Rather than adding this project as a dependency, consider [dropping](https://github.com/matryer/drop) this file into your project.
-
-## Example
-
-The following example examines how `resync.Once` could be used in a HTTP server situation.
-
-```go
-// use it just like sync.Once
-var once resync.Once
-
-// handle a web request
-func handleRequest(w http.ResponseWriter, r *http.Request) {
-	once.Do(func(){
-		// load templates or something
-	})
-	// TODO: respond
-}
-
-// handle some request that indicates things have changed
-func handleResetRequest(w http.ResponseWriter, r *http.Request) {
-	once.Reset() // call Reset to cause initialisation to happen again above
-}
-```
