I assume you're aware it's valid to have two initializers for the same
variable.? I often use -v and -verbose to both modify flagVerbose.
var flagVerbose bool
func init() {
boolVar(&flagVerbose,"v" ....
boolVar(&flagVerbose "verbose" ....
}
Other than that I don't see what your package is actually enhancing over
the current flag package. Could you please explain what advantage(s) you
believe you are providing. You might also want to re-visit the "usage"
function convention since that's pretty easy to use to accomplish the
"enough information" part.
