 Converts GPFS policy run logs to parquet files for easier aggregation and analysis.\n
 Works with data from /data/user, /data/user/home, /data/project, and /scratch
 The data are parsed and the directory beneath any of those listed above is set as the top-level
-directory ('tld'). The tld is then set as the index for the parquet file to improve aggregation speed
-
-If the full log is split into multiple parts, the full dataset will need to be repartitioned after all of
-the parts are converted to parquet to make sure all entries for each tld are in the same partition. This
-can be done with a separate script
