 3 | <h3>Introduction</h3>
 4 | Simple Shell script which can Obfuscate Code before pack, use for App, especially for iOS project. 
 5 | <br>
 6 | <h3>Usage</h3>
 7 | <p>Change the property or method name <b>AAA</b> as <b>ob_AAA_fus</b> and run script <b>obfusscript.sh</b> to obfuscate in the project.</p>
 8 | <p>Run script <b>deobfusscript.sh</b> to retore.</p>
 9 | 
10 | <p>You need to set these path Before running script.</p>
