Launching on Startup

Topframe works with launchd to run as an agent on startup. You can generate a plist file with topframe -agent, which you can write to a file and move into /Library/LaunchAgents:

$ topframe -agent > com.progrium.Topframe.plist
$ sudo mv com.progrium.Topframe.plist /Library/LaunchAgents

The generated plist will use the current binary location, so make sure it's in the right place before generating, or modify the plist file.
