    130: $             = 1 : The PetscOptionsInt() etc again call the PetscOptionsGetInt() etc (possibly getting new values), in addition the help message and
    131: $                   default values are printed if -help was given.
    132: $           When PetscOptionsObject.changedmethod is set this causes PetscOptionsPublishCount to be reset to -2 (so in the next loop iteration it is -1)
    133: $           and the whole process is repeated. This is to handle when, for example, the KSPType is changed thus changing the list of
