-    /// `exit()`  terminates the program and doesn't provide a
+    /// Detects calls to the `exit()` function which terminates the program.
-    /// stack trace.

+    /// Exit terminates the program at the location it is called. For unrecoverable

+    /// information. A normal termination or one with an error code should happen in
     /// the main function.

     /// ### Example
-    /// ```ignore

     /// std::process::exit(0)

+    /// ```ignore
