The use of [pflag](https://github.com/spf13/pflag/) in Viper does not preclude
the use of other packages that use the [flag](https://golang.org/pkg/flag/)
package from the standard library. The pflag package can handle the flags
defined for the flag package by importing these flags. This is accomplished
by a calling a convenience function provided by the pflag package called
AddGoFlagSet().
Example:
```go
package main
import (
"flag"
"github.com/spf13/pflag"
)
func main() {
pflag.CommandLine.AddGoFlagSet(flag.CommandLine)
pflag.Parse()
...
}
```
