Does it make sense to catch exceptions in the main(…)?

Question

I found some code in a project which looks like that :

int main(int argc, char *argv[])
{
  // some stuff

 try {
  theApp.Run();
 } catch (std::exception&a

Have a look at the C++ bible i.e. Stroustrup, he has an example which is also repeated in Applied C++ programming. The reasoning is:

int main(void)
{
     try
     {
          // your code 
     }
     catch ( /* YourPossibleExceptions i.e. barfs you expect may occur */ )
     {
     }
     catch ( ... ) // unexpected errors, so you can exit gracefully
     {
     }
}
