Advertise in the Startd's ClassAd the existence (or otherwise of the
file) something like
HasTheFlibbleFile = True
HasTheFlibbleFile = False
Then in your job submission file include in the requirementes
HasTheFlibbleFile == True
Obviously this is not automated, if you prefer that you can look at
things like Hawkeye to automate the setting of the attribute but the
basic principle remains the same...
