ControlPlane makes your computing environment context-sensitive. Reconfigure your machine based on what is going on or where you are at. Set the office printer as your default while in the office or enable the screensaver password when away from home. ControlPlane is a fork of MarcoPolo, which is now unsupported. Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
