+### Example usage ###
+```rust
+// Variables for arguments to fill
+let mut file = PathBuf::new();
+let mut out: Option<PathBuf> = None;
+let mut number = 0;
+
+// Set up arguments table
+enum Arg { Help, Number, File, Out }
+const OPTIONS: Opts<Arg> = Opts::new(&[
+  Opt::help_flag(Arg::Help, &["-h", "--help"]).help_text("Show this help and exit."),
+  Opt::value(Arg::Number, &["-n", "--number"], "value").help_text("Optionally specify a number (default: 0)"),
+  Opt::positional(Arg::File, "file").required().help_text("Input file."),
+  Opt::positional(Arg::Out, "out").help_text("Output destination (optional).")
+]).with_description("My simple utility.");
+
+// Parse the arguments
+match OPTIONS.parse_easy(|program_name, id, _opt, _name, arg| {
+  match id {
+    Arg::Help => {
+      OPTIONS.print_full_help(program_name);
+      return Ok(ParseControl::Quit);
+    }
+    Arg::Number => { number = str::parse(arg)?; }
+    Arg::File   => { file = arg.into(); }
+    Arg::Out    => { out = Some(arg.into()); }
+  }
+  Ok(ParseControl::Continue)
+}) {
+  ParseResult::ContinueSuccess => (),
+  ParseResult::ExitSuccess     => std::process::exit(0),
+  ParseResult::ExitError       => std::process::exit(1),
+}
+
+// Print the result variables
+println!("{file:?} -> {out:?} (number: {number:?})",
+  out = out.unwrap_or(file.with_extension("out")));
+```
