+"""Driver for Accu-Chek Mobile devices with reports mode.
+
+This driver expects a mountpoint as the device name, and will read the
+data off the CSV file found there. This means it is read-only access,
+but has no dependencies at all.
+
+The Accu-Chek Mobile meters should be set to "Reports" mode.
