+ * Manual Testing Instructions:
+ * 
+ * To validate the use_app_entitlements feature works correctly:
+ * 
+ * 1. Prepare test materials:
+ *    - An iOS app binary (.ipa or .app) with existing entitlements
+ *    - A provisioning profile for re-signing
+ *    - A valid code signing identity
+ * 
+ * 2. Test without use_app_entitlements:
+ *    rock sign:ios path/to/app.ipa --identity "Your Identity"
+ *    
+ * 3. Test with use_app_entitlements:
+ *    rock sign:ios path/to/app.ipa --use-app-entitlements --identity "Your Identity"
+ * 
+ * 4. Verify the difference:
+ *    - Extract entitlements from both signed apps using:
+ *      codesign -d --entitlements - --xml signed-app.app
+ *    - Compare the entitlements to see that app-specific entitlements 
+ *      (like keychain-access-groups, iCloud services) are preserved
+ *      when using --use-app-entitlements
+ * 
+ * Expected behavior:
+ * - Without flag: Only provisioning profile entitlements
+ * - With flag: Merged entitlements (profile + preserved app entitlements)
