// .NAME vtkBreakPoint - Utility function to debug with gdb and MPI.
// .SECTION Description
// Wherever you need to set a break point inside a piece of code run by MPI,
//
// Step 1: call vtkBreakPoint::Break() in the code.
// Step 2: start MPI, each process will display its PID and sleep.
// Step 3: start gdb with the PID: gdb --pid=<PID>
// Step 4: set a breakpoint at the line of interest: (gdb) b <option>
// Step 5: go out of the sleep: (gdb) set var i=1
// Original instructions at the OpenMPI FAQ:
// http://www.open-mpi.de/faq/?category=debugging#serial-debuggers
// - 6 Can I use serial debuggers (such as gdb) to debug MPI applications?
// - 6.1. Attach to individual MPI processes after they are running.
//
// .SECTION Implementation
// This function is in Common, not in Parallel because it does not depend on
// MPI and you may want to call vtkBreakPoint::Break() in any class of VTK.
