    To get started, copy one of these configurations to ~/.offlineimaprc:
    * minimal configuration:
        cp -n #{prefix}/offlineimap.conf.minimal ~/.offlineimaprc

    * advanced configuration:
        cp -n #{prefix}/offlineimap.conf ~/.offlineimaprc


    To launch on startup and run every 5 minutes:
    * if this is your first install:
        mkdir -p ~/Library/LaunchAgents
        cp #{prefix}/org.offlineimap.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/org.offlineimap.plist

    * if this is an upgrade and you already have the org.offlineimap.plist loaded:
        launchctl unload -w ~/Library/LaunchAgents/org.offlineimap.plist
        cp #{prefix}/org.offlineimap.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/org.offlineimap.plist
