What is the 'screen' utility?

The 'screen' system utility is included the project package to enable node administrators and project developers to collaborate. This is along the lines of the "teach them to fish" philosophy. By sharing an ssh terminal window while a developer makes configuration changes the node administrator gains the knowledge to do it themselves and to help others.

Basically one user logs in as root and issues the command 'screen' and then a second second root user issues 'screen -x'. The result is that they both can see and use a shared terminal window.
