 The following code demonstrates a program that waits for an interrupt signal and removes a temporary file when it occurs.
 
 ```
-    package main
-    
-    import (
-        "io/ioutil"
-        "os"
-        "os/signal"
-    )
-    
-    func main() {
-        f, err := ioutil.TempFile("", "test")
-        if err != nil {
-            panic(err)
-        }
-        defer os.Remove(f.Name())
-        sig := make(chan os.Signal, 1)
-        signal.Notify(sig, os.Interrupt)
-        <-sig
-    }
