/// Calling this method establishes a module as being the main module of the

/// loaded as if require()'d and its "module" property will be set as the
/// "main" property of this require() instance. You have to call this method
/// before the module has been loaded (that is, the call to this method must
/// be the first to require the module and thus trigger its loading). Note
/// that the main module will execute in its own scope and not in the global
/// scope. Since all other modules see the global scope, executing the main
/// module in the global scope would open it for tampering by other modules.
