// Forward Multiplicity Detector based on Silicon wafers.
//
// This class is a singleton that handles various parameters of
// the FMD detectors.
+// The manager normally serves the parameters from the Conditions
+// Database (CDB). These are retrivied by the member function
+// `Init'. Optionally, the class can serve hard-coded constants, if
+// no CDB is available.
