// Data
Group {
    files: "images/*"
    qbs.install: true
    qbs.installDir: "data"
}

// Images
Group {
    files: "images/*"
    fileTags: "img"
}

// Data
Group {
    fileTagsFilter: "img"
    //fileTagsFilter: ["img", "audio", "txt"]
    qbs.install: true
    qbs.installDir: "data"
}

// Bin
Group {
    fileTagsFilter: "application"
    qbs.install: true
    qbs.installDir: "bin"
}
