* This file contains MERGED version of PHP QR Code library. |

7
|
|
|
* It was auto-generated from full version for your convenience. |
|

|
|
|

|
9
|
|
|
* This merged version was configured to not require any external files, |
|
10
|
|
|
* with disabled cache, error logging and weaker but faster mask matching. |
|
11
|
|
|
* If you need tune it up please use non-merged version. |
