19 // Implementation of the heavy-flavour vertexing analysis class
20 // Candidates are stored in the AOD as objects deriving from AliAODRecoDecay.
21 // To be used as a task of AliAnalysisManager by means of the interface
22 // class AliAnalysisTaskSEVertexingHF.
23 // An example of usage in the macro AliAnalysisTaskSEVertexingHFTest.C.
