## Supporting Go flags when using pflag
In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
to support flags defined by third-party dependencies (e.g. `golang/glog`).
**Example**: You want to add the Go flags to the `CommandLine` flagset
```go
import (
goflag "flag"
flag "github.com/spf13/pflag"
)
var ip *int = flag.Int("flagname", 1234, "help message for flagname")
func main() {
flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
flag.Parse()
}
```
## More info
You can see the full reference documentation of the pflag package
