+# cluster. The results are collected in two folders:
+# ~/ipstats/west, ~/ipstats/east
+# These folders conatins one subfolder per instances, with
+# names such as aa01-us-rtv, i.e. <instance>-<country>-<city>.
+# The cluster name is the tuple <country-city>.
+# The instance folder contain a file per day, e.g.
+# ~/ipstats/west/aa01-us-rsv/20240319-ipstats.csv
+# The script lists the instances and daily summaries available
+# under "east" or "west", computes a list of instance per clusters,
+# and compute a list per cluster of instance file names per day.
