-UserAgent is a Go library that parses HTTP User Agents.
-
-## Usage
-
-~~~ go
-package main
-
-import (
-    "fmt"
-
-    "github.com/mssola/user_agent"
-)
-
-func main() {
-    // The "New" function will create a new UserAgent object and it will parse
-    // the given string. If you need to parse more strings, you can re-use
-    // this object and call: ua.Parse("another string")
-    ua := user_agent.New("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11")
-
-    fmt.Printf("%v\n", ua.Mobile())   // => false
-    fmt.Printf("%v\n", ua.Bot())      // => false
-    fmt.Printf("%v\n", ua.Mozilla())  // => "5.0"
-
-    fmt.Printf("%v\n", ua.Platform()) // => "X11"
-    fmt.Printf("%v\n", ua.OS())       // => "Linux x86_64"
-
-    name, version := ua.Engine()
-    fmt.Printf("%v\n", name)          // => "AppleWebKit"
-    fmt.Printf("%v\n", version)       // => "537.11"
-
-    name, version = ua.Browser()
-    fmt.Printf("%v\n", name)          // => "Chrome"
-    fmt.Printf("%v\n", version)       // => "23.0.1271.97"
-
-    // 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
