Notes
Use # for lines that are comments and which should be ignored.
Usually, instead of using this command, one should list the file name in the call to PetscInitialize(), this insures that certain options
such as -log_view or -malloc_debug are processed properly. This routine only sets options into the options database that will be processed by later
calls to XXXSetFromOptions() it should not be used for options listed under PetscInitialize().
