[UrbanSim-Users] warning/error(?) during flushing

Hello,

I pulled down the latest development release of UrbanSim today. At
first blush, our model seems to run well. However, I'm getting the
following warning/error messages at the end of each year:

             Writing datasets to cache for year 1991: started on Fri
Apr 25 14:48:03 2008
                 Flushing travel_data
                 C://urbansim_cache

                 Flushing vacant_land_and_building_type

                 Flushing zone
                 C://urbansim_cache
\run_117.2008_04_25_14_45\1991\zones doesn't exist and is created

What does "doesn't exist and is created" mean exactly? Does this
indicate an error condition, or is it merely an informational message
(i.e. is UrbanSim say, "By the way, I cached this dataset for you.")?

Thanks,
