Hi folks,

please do not just check out the mdc1 production and run the production 
scripts. Those scripts modify our file catalog and actually can 
overwrite the files from the mdc1 production. E.g. you'll find 3 copies 
of DST_HF_CHARM_pythia8-0000000001-00000.root in the file catalog, one 
from the mdc1 production on disk but another one from some private 
running which then was copied to dCache. If you request the files via 
the script it's random which disk copy you'll get (and they are different).

I am cleaning this up now - but please do not run those macros (at least 
comment out the Enable::PRODUCTION). The Production_MoveOutput(); is 
where the files are added to the file catalog. Copying to dCache is a 
separate step which uses the file catalog where the wrong files can be 
picked and are then copied to dCache.

Chris
