How about something like

        #include <sstream>
        
        void HandleLinkLine(const char* str)
        {
           std::stringstream s(str);
           while (!s.eof()) { 
             std::string comp;
             s >> comp;
             if (s.bad()) break;
             
             if (comp[0] != '-') {
                Warning("LoadLibraryList", "Unknown component %s in %s", comp.c_str(), str);
        	continue;
             }
        
             std::string dir_or_file = comp.substr(2,comp.size()-2);
             if (comp[1] == 'L') {  
                std::string path = gSystem->GetDynamicPath();
                path += ':'; path += dir_or_file;
                gSystem->SetDynamicPath(path.c_str());
             }
             else if (comp[1] == 'l') { 
                std::string lib("lib");
                lib += dir_or_file;
                lib += ".so";
                gSysten->Load(lib.c_str());
             }
             else {
                Warning("LoadLibraryList", "Unknown option %s in %s", comp.c_str(), str);
                continue;
             }
           }
        }
            

Perhaps code like this should be added to the command line handling, so that one could execute ROOT with a command line like

        root -L/path/to/libs -llibrary -lfoo
        

which could make batch processing easier.

Yours,
