[ BUILD # : 200509151800 ]
[ JDK VERSION : 1.5.0_02 ]

Try feedreader-suite example, and "build ZIP Distribution". When 
running the generated application it creates a folder ${HOME}/$
{APPNAME}/dev.

I think should create .{APPNAME}/dev that User don't see the 
folder. For a better Mac like support it should add this:
etc/feedreader.conf:
default_mac_userdir="${HOME}/Library/Application Support/$
{APPNAME}/dev"

replace in bin/feedreader:
userdir=${default_userdir}

with:
case "`uname`" in
    Darwin*)
        userdir=${default_mac_userdir}
        ;;
    *)
        userdir=${default_userdir}
        ;;
esac

This should be default for all application brandings.
