/** @page LEVEL1 Introduction The responsibility for this document lies with the Simulation and Graphics Branch (ER7) of the Automation, Robotics and Simulation Division of the NASA JSC Engineering Directorate. The purpose of this document is to provide %Trick simulation developers and users with a detailed user’s reference guide on how to install %Trick, use %Trick processors and utilities, and how to operate a simulation from execution to data post processing. To see how to build a simulation from scratch, refer to the %Trick Tutorial document. For details about the high level design of %Trick, refer to the %Trick Design document. Details of specific NASA programmatic math models and simulations will not be addressed in this document. */
