    ],
    '自定义的 soar 路径'
);

// Final run: /Users/yaozm/Documents/develop/soar-php/bin/soar.darwin-amd64 '-version=true'
$soar->clone() // Clone soar and avoid the option to manipulate the original soar.
    ->addVersion(true) // Add -version value of the option is `true`

    ->mergeVersion(true) // Merge -version value of the option is `true`
    ->onlyVersion() // Only keep -version option
    ->dump() // Dump debug information
    ->run(); // Run
