+// AliMUONDigitizerv1 implements a full digitizer to digitize digits directly
+// from hits. It also performs merging over several input streams.
+// The first input stream is assumed to be the signal and all other input
+// streams are assumed to be background. SDigits are never generated by this
+// digitizer and one should use the AliMUONSDigitizerv1 for that task.
+//
+// NOTE: This digitizer will become depricated in the future in favour of
+// AliMUONSDigitizerv1 and AliMUONDigitizerv2.
