Changes from previous version:

Enhancements

• support -x-turn-echo-off to turn the echo off on each example to be
  executed (#245). This option is disabled by default on 10.5.x to not
  break backward compatibility and it is intentionally undocumented.
  Expected to be formally enabled on 11.0.0

What's Changed

• Issue 245 turn echo off on each exec for 10.5.4 by @eldipa in #255
