65    Synopsis: PetscErrorCode PetscOptionsBegin(MPI_Comm comm,const char prefix[],const char title[],const char mansec[])
66 
67     Collective on MPI_Comm
68 
69   Input Parameters:
70 +   comm - communicator that shares GUI
71 .   prefix - options prefix for all options displayed on window
72 .   title - short descriptive text, for example "Krylov Solver Options"
73 -   mansec - section of manual pages for options, for example KSP
74 
75   Level: intermediate
76 
77   Notes: Needs to be ended by a call the PetscOptionsEnd()
78          Can add subheadings with PetscOptionsHead()
79 
80   Developer notes: PetscOptionsPublish is set in PetscOptionsCheckInitial_Private() with -options_gui. When PetscOptionsPublish is set the
81 $             loop between PetscOptionsBegin() and PetscOptionsEnd() is run THREE times with PetscOptionsPublishCount of values -1,0,1 otherwise
82 $             the loop is run ONCE with a PetscOptionsPublishCount of 1.
83 $             = -1 : The PetscOptionsInt() etc just call the PetscOptionsGetInt() etc
84 $             = 0  : The GUI objects are created in PetscOptionsInt() etc and displayed in PetscOptionsEnd() and the options
85 $                    database updated updated with user changes; PetscOptionsGetInt() etc are also called
86 $             = 1 : The PetscOptionsInt() etc again call the PetscOptionsGetInt() etc (possibly getting new values), in addition the help message and
87 $                   default values are printed if -help was given.
