Comment (by bmundim):

 A few issues/questions for discussion:

 1) When running the test suites I got a message that it is not runnable
 for EinsteinExact:

 No runnable testsuites in arrangements: CactusBase CactusConnect CactusDoc
 CactusElliptic CactusIO CactusPUGH EinsteinBase EinsteinEOS EinsteinUtils
 ExternalLibraries TAT KrancNumericalTools EinsteinExact

 However EinsteinExact does have a test suite at

 EinsteinExact/EinsteinExact_Test/test/ShiftedGaugeWave.par

 EinsteinExact_Test is correctly symbolically linked in the arrangements
 directory. Any ideas what could be going wrong here?

 2) When I ran the ShiftedGaugeWave.par test case I found a bit suspicious
 that the  values output were exactly one or zero for gxx, kxx, alp or
 betax. Was this intentional? Doesn't it make the test too trivial?

 3) Note too that ADMBase::dtalp and ADMBase::dtbetax are not output at all
 despite enlisted to do so. I guess this is happening because
 initial_dtlapse and initial_dtshift default to "none". So we need to
 set those parameters in the test par file. In any case, I added the
 following parameters to the par file and I got an output with non trivial
 values:

 ADMBase::initial_data    = ShiftedGaugeWave
 ADMBase::initial_shift   = ShiftedGaugeWave
 ADMBase::initial_lapse   = ShiftedGaugeWave
 ADMBase::initial_dtshift = ShiftedGaugeWave
 ADMBase::initial_dtlapse = ShiftedGaugeWave

 4) In the documentation it says that the code ignores initial_shift,
 initial_lapse, initial_dtshift and initial_dtlapse. Per example above, I
 don't think this is true.

 5) There are a few instances of "CCTK_INT ierr = 0;"
 declarations/initializations that are not used afterwards. That could be
 taken out to avoid compiler warning complaints.
