  Description("AWS CloudFormation Sample Template Redmine_Simple: Redmine is a  flexible project management web application which includes a gantt chart, calendar, wiki, forums, multiple roles, and email notification. You can sign-in with the default account 'admin' and the default password 'admin'. This template installs a Redmine stack using a single EC2 instance with a local MySQL database for storage. It demonstrates using the AWS CloudFormation bootstrap scripts to install the packages and files necessary to deploy the Redmine, Rails, MySQL and all dependent packages at instance launch time. **WARNING** This template creates an Amazon EC2 instance. You will be billed for the AWS resources used if you create a stack from this template.")
