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: libafl_libtool.rs
    path of file: ./repos/LibAFL/fuzzers/libfuzzer_libpng_launcher/src/bin
    
    the code of the file until where you have to start completion: use std::env;

u
    
pub fn main() {
    let args: Vec<String> = env::args().collect();
    if args.len() > 1 {
        let mut cc = LibtoolWrapper::new();
        if let Some(code) = cc
            // silence the compiler wrapper output, needed for some configure scripts.
            .silence(true)
            .parse_args(&args)
            .expect("Failed to parse the command line")
            .add_configuration(Configuration::GenerateCoverageMap)
            .add_configuration(Configuration::Compound(vec![
                Configuration::GenerateCoverageMap,
                Configuration::CmpLog,
            ]))
            .add_configuration(Configuration::Compound(vec![
                Configuration::GenerateCoverageMap,
                Configuration::AddressSanitizer,
            ]))
            .add_configuration(Configuration::Compound(vec![
                Configuration::GenerateCoverageMap,
                Configuration::UndefinedBehaviorSanitizer,
            ]))
            .run()
            .expect("Failed to run the wrapped libtool")
        {
            std::process::exit(code);
        }
    } else {
        panic!("LibAFL libtool: No Arguments given");
    }
}
