示例1: operator

if (argvec.size() != 4) {
return interp->RunCommand("help alias") + "\n(Please refer to the help documentation for proper invocation)";
}
// First get the alias name
std::string cmd = argvec[1];
std::vector<std::string> cmds;
// Next get the arguments.
Chain argSrc = argvec[2].c_str();
