Overview

The RPN calculator project serves as an exploration playground wherein a developer can learn a bit about the software development process in a manner that can be catered towards the developer and the development environment (company norms), etc. The core algorithmic work of this project is nothing more than what is defined with 'Reverse Polish Notation': http://en.wikipedia.org/wiki/Reverse_Polish_notation

The task list will start small, and then will build in a fashion that conveys software development principles.

Installation

• All operations assume the Eclipse STS IDE (3.2+); Ensure extensions described here are in place: http://www.grails.org/STS+Integration
• Setup basic Eclipse Git settings (Preferences > Git). Most notably, setup a Default respository folder
• File > Import... > Git > Repositories from GitHub > (search for rpnmde) > (click repository) > Finish
• Takes a few seconds to pull down respository from GitHub
• File > Import... > Grails > Grails Project > (browse to your Git repository) > Finish
• Takes a few seconds to setup project synch Git respository with Eclipe
• Right click on project > Team... > Share Project... > Git > (it should detect your Git details> Finish
