Hi JMC and Patrick

Sounds good — just had a quick look and this wont be at all hard to do. 

However it would be nice to keep it in exf monitor…..would it be OK to keep two USE_EXFCO2 in 
exf_monitor.F
one for BLING_VARS.h 
and one for 
      IF ( apco2file .NE. ' ' ) THEN
          CALL MON_WRITESTATS_RL( 1, apco2, '_apco2',
     &             maskInC, maskInC, rA , drF, dummyRL, myThid )
        ENDIF

Everything else is easily migrated to /pkg/bling

And just curious, but where are you hiding /pkg/gud?

Thanks!
Matt
