+# In this exapmple we have a function `publish_every_2secs` publishing a
+# message every 2 seconds to topic `hopping_topic`.
+# We have created an agent `print_windowed_events` consuming events from
+# `hopping_topic` that mutates the windowed table `hopping_table`.
+
+# `hopping_table` is a table with hopping (overlaping) windows. Each of
+# its windows is 10 seconds of duration, and we create a new window every 5
+# seconds.

+# Since we produce an event every 2 seconds and our windows are 10
+# seconds of duration we expect different the following results per method
+# called in `WindowWrapper`:
+# - now(): Gets the closest value to current local time. It will always be
+# between 1 and 3.
+# - current(): Gets the value relative to the event's timestamp. It will
+# always be between 1 and 3.
+# - value(): Gets the value relative to default relative option. It will
+# always be between 1 and 3.
+# - delta(30): Gets the value of window 30 secs before the current event. For
+# the first 20 seconds it will be 0 and after second 30 it will always be 5.
