Reads all search templates from LaunchBar and outputs a plist formatted to be used with Alfred (complete with the custom searches you already added to Alfred, if any.)
Requires the plist gem, so run gem install plist first.
Quit Alfred. Then, from Terminal:
git clone https://github.com/dipnlik/launchbar2alfred.git
cd launchbar2alfred
gem install plist
./merge_searches > ~/Desktop/customsites.plist
open "$HOME/Library/Application Support/Alfred/customsites"
You should now have a Finder window showing Alfred's configuration folder. Backup the customsites.plist file in this folder (hint: right click, Compress...) and replace it with the one in your desktop.
