This is encapsulated in a CMPITclPackagedCommand
as it is part of the parameter package of commands. It only executes in the
event sink pipeline as pseudo parameters are computed when all ordinary
parameters have been computed as a step in the event sink pipeline prior to
actual histograming. All other processes return TCL_OK
and an empty result.
