Gyoto is a framework for computing geodesics in curved space-times. The gyoto-mpi-worker helper program
is not meant to be executed directly by the user. It is spawned by the MPI frawework when using multi-
processing. It does not process any command-line parameter, but passes them to MPI_Init(3). gyoto-mpi-worker is bound to a specific version of the Gyoto application binary interface (ABI). To allow for co-
installation of several versions of the Gyoto library, the SO information digits are appended to the
executable name.
