Scheduled Launching/Quitting Applications

On our Mac mini, I wanted to schedule an application to launch in the morning, and quit at night.  I was able to pretty easily configure launchd and AppleScript to do this.

For example, if I wanted to launch TextEdit, I would create these AppleScripts, and saved them as applications.

tell application "TextEdit"
    activate
end tell

tell application "TextEdit"
    quit
end tell

Then, I scheduled these applications to be launched at the specified time with launchd using Lingon.
