PERMISSION IS GRANTED TO USE OR MODIFY THIS SCRIPT FREE OF CHARGE
AS LONG AS THE ABOVE COPYRIGHT NOTICE REMAINS INTACT.
NO WARRANTY IS PROVIDED. PLEASE DECIDE AND USE AT YOUR OWN RISK.

This script (${_scriptver}) will download and install pixelserv-tls beta version ${_beta}.
The script will guide you through and automate the process.

The following Entware-ng/3x architectures are currently provided:

   1. armv7  (RT-AC56U/68U/etc)  - backup prod versoin and install 32-bit ${_beta}
   2. mipsel (RT-N66U/AC66U/etc) - backup prod version and install 32-bit ${_beta}
   3. armv8  (RT-AC86U/etc)      - backup prod version and install 64-bit ${_beta}
   4. restore  - revert back to prod version and clean up test directory

Type 1, 2, 3, or 4 to proceed or anything else to quit:
