// Example of a simple script creating 3 threads.
// This script can only be executed via ACliC: .x threads.C++.
// Before executing the script, load the Thread library with:
//   gSystem->Load("libThread");
// This is not needed anymore due to the rootmap facility which
// automatically loads the needed libraries.
