-=== Package
-
-A package describing the AXIS packet at the module output is present.
-It helps to automatically pack or unpack the packet (functions _bpmpacket2slv()_ or _slv2bpmpacket()_ ).
-A zero packet (_C_BPMPACKET_ZERO) is also declared.

 == TODO/Future of this module
 
-* Remove the pkg bpm stream. It is not that handy.
-* Add configuration feature to allow the choice of the transceiver (for now only X0Y4 GTH).
-* The application should be able to instanciate several transceiver interface, with one decoder for each.
-* At SOLEIL, the BPM electronics will change by 2025.
-At that point, it will be necessary to change the *Transceivers* and *Protocol decoder* blocs to match the new equipments.
+* This module will fade out of usage as SOLEIL moves to the next generation of BPM electronics
