Mail unread menu and 5.3

Another thing that broke on an OSX upgrade was mail unread menu (http://loganrockmore.com/mailunreadmenu/) which I really like.  So with a little help from http://stib.posterous.com/how-to-fix-unsupported-plugins-after-upgradin I was able to write the following script (though you can cut and paste them directly into a Terminal (Applications -> Utilities -> Terminal) window).

#! /bin/sh

a=`defaults read /Applications/Mail.app/Contents/Info PluginCompatibilityUUID`
b=`defaults read /System/Library/Frameworks/Message.framework/Resources/Info PluginCompatibilityUUID`

for i in ~/Library/Mail/Bundles*/MailUnreadMenu.mailbundle/Contents/Info.plist
do
    echo "$i"
    echo "${i%%.plist}"

    defaults write "${i%%.plist}" SupportedPluginCompatibilityUUIDs -array-add "$a";
    defaults write "${i%%.plist}" SupportedPluginCompatibilityUUIDs -array-add "$b";
    plutil -convert xml1 "$i"
done

Then a

mv ~/Library/Mail/Bundles\ \(Disabled\)/MailUnreadMenu.mailbundle/ ~/Library/Mail/Bundles

Made things right again.
