128: $             the loop is run ONCE with a PetscOptionsPublishCount of 1.
129: $             = -1 : The PetscOptionsInt() etc just call the PetscOptionsGetInt() etc
130: $             = 0  : The GUI objects are created in PetscOptionsInt() etc and displayed in PetscOptionsEnd() and the options
131: $                    database updated updated with user changes; PetscOptionsGetInt() etc are also called
132: $             = 1 : The PetscOptionsInt() etc again call the PetscOptionsGetInt() etc (possibly getting new values), in addition the help message and
133: $                   default values are printed if -help was given.
134: $           When PetscOptionsObject.changedmethod is set this causes PetscOptionsPublishCount to be reset to -2 (so in the next loop iteration it is -1)
135: $           and the whole process is repeated. This is to handle when, for example, the KSPType is changed thus changing the list of
136: $           options available so they need to be redisplayed so the user can change the. Chaning PetscOptionsObjects.changedmethod is never
