E6  On compiling Fortran code I get errors like "dummy argument CCTK_DIM has
    not been given a type", but I'm not using CCTK_DIM in the routine?

    Check if you have passed CCTK_ARGUMENTS in the argument list for the
    routine, is do you must have a line

    DECLARE_CCTK_ARGUMENTS

    in your declarations section.

E7  If I have two grid array groups with identical sizes (and ghost zones,
    distributions, etc.), are they guaranteed to be distributed in the same
    way?  That is, can I count on the fact that their local shapes (lsh)
    will be the same?  It is true empirically. What if the grid arrays have
    different variable types or numbers of time levels?

    Yes to all.

D10 Output to screen using the Info IO method of IOBasic doesn't work.

    I want to watch min/max values for 'wavetoy::phi' during a cactus run
    on stdout.  For that, I added

    IOBasic::outInfo_every = 10
    IOBasic::outInfo_vars  = "wavetoy::phi"

    to my parameterfile. Thorn IOBasic is active, but I only get the
    iteration number and coordinate time printed to screen.

    You need to activate a thorn which implements the min/max reductions,
    for example CactusPUGH/PUGHReduce.

G1  How can I build the ThornGuide documentation for single thorns or
    arrangements?

    Give the names of the thorns or arrangements on the make line, e.g.

    gmake ThornGuide THORNS="CactusBase/Boundary"

    gmake ThornGuide ARRANGEMENTS="CactusBase"
