root.parseAndExecute(arguments);
}

Command _root() {
final parser = ArgParser()
..addFlag(

help: "Print this usage information",
)
..addFlag(
"version",
abbr: "v",
negatable: false,
help: "Print the version",

return Command(
help: "Usage: wrapper_args [<subcommand>] [<options>]",
parser: parser,
execute: (command, results) {
if (results["help"]) {
print("${command.usage}");
} else if (results["version"]) {
print("version 1.0.0");
}
},

Command _client() {
final parser = ArgParser()
..addFlag(
