Request a small example of how to use getopt to accomplish the following:
[1] program subcommand //process subcommand with default arguments if any
[2] program -h subcommand //output help information about subcommand
[3] program subcommand --option1 --option2 true option3=log.txt //
process subcommand with user specified options
import std.getopt;
void main(string[] args)

bool help;
getopt(args,
"h|help", &help,

if (args.length == 1)

// Print general help and list of commands

default:

Thank you very much.
