Qapla Chess Engine Tester 0.1.0

This is a tool to test chess Engines before delivery.
Its purpose is to detect protocol flaws in chess engines. I consider an engine tester successful if engines that pass its tests run flawlessly in all major GUIs and tournament managers.
Currently, it supports UCI (not WinBoard) and does not yet support pondering.
I'm interested in feedback, especially about publicly available engines that fail in certain GUIs — this helps me improve the tester further.

It is only available for Windows currently.
