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: wasm_size_bench.rs
    path of file: ./repos/perseus/scripts
    
    the code of the file until where you have to start completion: // This benchmark tests the final, release-mode, optimized size of the given example to identify regressions

use std::process::Command;
use std::io::Write;

fn main() {
    let args: Vec<String> = std::env::args().collect();

    let exit_code = match output.status.code() {
        Some(exit_code) => exit_code,         // If we have an exit code, use it
        None if output.status.success() => 0, // If we don't, but we know the command succeeded, return 0 (success code)
