+// The hook will set the icon size to 512 for all icons with a size of 0.
+// The hook can be removed once:
+// 1. The proper fix (https://github.com/develar/app-builder/pull/71) is merged.
+// 2. New versions of app-builder and app-builder-bin are released.
+// 3. A version of electron-builder with the fixed app-builder-bin is released.
+// 4. The electron-builder dev dependency is updated.
