 For example, `js/main.js` revisioned to `js/main.9d713a59.js` will also have `js/main.js.map` revisioned to the same hash `js/main.9d713a59.js.map`.

+Type: `boolean`  
+Default: `false`
+
+This option is useful when you are only interested about having a map of the transformation of the filename, which means the summary will only output the basename.
+
+For example you would have the following map, without taking into account which directories original and revved files would be.
+```

+  'img2.png': 'img2.060b1aa6.png'
