-/// \brief Use this to get all registered SubCommands from the provided parser.
-///
-/// \return A range of all SubCommand pointers registered with the parser.
-///
-/// Typical usage:
-/// \code
-/// main(int argc, char* argv[]) {
-///   llvm::cl::ParseCommandLineOptions(argc, argv);
-///   for (auto* S : llvm::cl::getRegisteredSubcommands()) {
-///     if (*S) {
-///       std::cout << "Executing subcommand: " << S->getName() << std::endl;
-///       // Execute some function based on the name...
-///     }
-///   }
-/// }
-/// \endcode
-///
-/// This interface is useful for defining subcommands in libraries and
-/// the dispatch from a single point (like in the main function).
