You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.rs
    path of file: ./repos/cavernos/cli/src
    
    the code of the file until where you have to start completion: mod subcommands;
mod manifest;

use structopt::StructOpt;

use subcommands::new::{NewOpts, new_command};
use subcommands::package::{PackageOpts, package_command};
use subcommands::run::{RunOpts, run_command};

#[derive(StructOpt, Debug)]
#[structopt(name = "cavernos")]
enum Cli {
  #[structopt(name = "new", about = "Create a new project from a template")]
  New(NewOpts),
  
  #[structopt(name = "package", about = "Bundle up your project into a distributable package")]
  Package(PackageOpts),

  #[structopt(nam
    
fn main() {
  let subcommand = Cli::from_args();
  
  match subcommand {
    Cli::New(opts) => new_command(opts),
    Cli::Package(opts) => {
      match package_command(opts) {
        Ok(()) => (),
        Err(msg) => {
          eprintln!("Packaging error: {}", msg);
          std::process::exit(1);
        }
      }
    },
    Cli::Run(opts) => {
      match run_command(opts) {
        Ok(()) => (),
        Err(msg) => {
          eprintln!("Run error: {}", msg);
          std::process::exit(1);
        }
      }
