// Package flag provides flag definitions for the suidhelper package.
//
// It does NOT depend on any packages outside the Go standard library.
// This allows v.io/core/veyron/lib/testutil to depend on this
// package, thereby ensuring that the suidhelper flags are defined
// before the flag.Parse call in testutil.init is made.
//
// This is a hack! This file should go away once testutil.init
// is changed to not parse flags in init().
// TODO(cnicolaou,ashankar): See above!
