// Wrap makes an Error from the given value. If that value is already an
// error then it will be used directly, if not, it will be passed to
// fmt.Errorf("%v"). The skip parameter indicates how far up the stack
// to start the stacktrace. 0 is from the current call, 1 from its caller, etc.
Wrap makes an Error from the given value . If that value is already an error then it will be used directly if not it will be passed to fmt . Errorf ( %v ) . The skip parameter indicates how far up the stack to start the stacktrace . 0 is from the current call 1 from its caller etc .
