/* === Example to strip simulator archs for Apple Store Submission ===
 *
 * Step 1. extract all archs first
 *    `node ios_arch.js --extract`
 * Step 2. re-package binary without simulator archs
 *    `node ios_arch.js --device`
 * 
 * That's it!
 * Remember to delete generated/backed up files (WebRTC-*) from step 1 if needed
 *
 * === How to Verify ===
 *
 * You can check current archs use this command:
 *     `file $YOUR_PATH/WebRTC.framework/WebRTC`
