+ * manifest", based on the options you provide.
+ *
+ * The manifest is injected into the `swSrc` file, and the placeholder string
+ * `injectionPoint` determines where in the file the manifest should go.
+ *
+ * The final service worker file, with the manifest injected, is written to
+ * disk at `swDest`.

+ * This method will not compile or bundle your `swSrc` file; it just handles
