Author: gladky_anton Date: 2009-07-27 17:00:20 +0200 (Mon, 27 Jul 2009) New Revision: 1887
Added: trunk/pkg/common/Engine/DeusExMachina/PressTestEngine.cpp trunk/pkg/common/Engine/DeusExMachina/PressTestEngine.hpp Modified: trunk/pkg/common/SConscript Log: 1. Added PressTestEngine for simulating presses. Can be used and for PointLoadTest simulations.
