#=================================================

### If the app uses nginx as web server (written in HTML/PHP in most cases), the final path should be "/var/www/$app".

### you can make a backup of this file before modifying it again if the admin had modified it.

### For security reason, any app should set the permissions to root: before anything else.

### that really need such authorization.
