func main() {

    ua := user_agent.New("Mozilla/5.0 (Linux; U; Android 2.3.7; en-us; Nexus One Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1")

    fmt.Printf("%v\n", ua.Mobile())  // => true
    fmt.Printf("%v\n", ua.Bot())     // => false
    fmt.Printf("%v\n", ua.Mozilla()) // => "5.0"

    fmt.Printf("%v\n", ua.Platform()) // => "Linux"
    fmt.Printf("%v\n", ua.OS())       // => "Android 2.3.7"

    name, version := ua.Engine()
    fmt.Printf("%v\n", name)    // => "AppleWebKit"
    fmt.Printf("%v\n", version) // => "533.1"

    name, version = ua.Browser()
    fmt.Printf("%v\n", name)    // => "Android"
    fmt.Printf("%v\n", version) // => "4.0"

    // Let's see an example with a bot.
    ua.Parse("Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)")

    fmt.Printf("%v\n", ua.Bot()) // => true

    name, version = ua.Browser()
    fmt.Printf("%v\n", name)    // => Googlebot
    fmt.Printf("%v\n", version) // => 2.1
}
