Package flag implements command-line flag parsing.

# Usage

Define flags using [flag.String], [Bool], [Int], etc.

This declares an integer flag, -n, stored in the pointer nFlag, with type *int:

	import "flag"
	var nFlag = flag.Int("n", 1234, "help message for flag n")

If you like, you can bind the flag to a variable using the Var() functions.

	var flagvar int

// limitations under the License.

package flag

import (
	"os"
	"strings"
	"time"

	"github.com/spf13/pflag"
)

// Flaggable defines the set of types that can be flags.
// This is not exhaustive; add more as needed
type Flaggable interface {
	string | bool | uint16 | time.Duration
}
