Introduction

Welcome to Rational Rose RealTime Evaluation Edition. Rational Rose RealTime is a Unified Modeling Language (UML) development software design tool that lets developers capture and communicate their software designs using the UML. Rational Rose RealTime can be used to develop C, C++ and Java applications for a wide range of targets. A UML model compiler ensures that the design is always in-sync with the implementation. Rational Rose RealTime can generate applications for a wide range of targets including Unix and Windows operating systems, embedded Real-Time Operating Systems (RTOS), and even bare systems without an operating system. 

This C++ Evaluation Edition of Rational Rose RealTime has been configured for use with Microsoft Visual Studio 6 for Windows NT/2000/XP target platforms. If you do not have Microsoft Visual Studio 6, the Evaluation Edition will also work with Red Hat Cygwin 1.3.1 GNU tools for Microsoft Windows NT/2000/XP.  This document explains how to download and install the Cygwin tools for use with Rational Rose RealTime Evaluation Edition.
