-Reading DAQ Data
-================
-
-The following example shows how to access hits in a ROOT file which is coming
-from the detector and written by the `JDataWriter` application.
-
-Such a file is usually called "KM3NET_00000001_00000002.root", where the first
-number is the detector ID and the second the run number.

-# Accessing the event tree
-# ------------------------
-# Just pass a filename to the reader class and get access to the event tree
-# with:
-
-f = km3io.OnlineReader("samples/daq_v1.0.0.root")
-

-# Note that only some meta information is read into memory.
-#
-# Printing it will simply tell you how many events it has found. Again, nothing
-# else is read yet:
-
-print(f.events)
