Detailed Description

The Application Manager class.

The main purpose of the Application Manager is to steer any data processing application. This includes all data processing applications for LHCb data in all stages: simulation, reconstruction, analysis, high level triggers, etc. Specific implementations of the ApplicationMgr will be developed to cope with the different environments (on-line, off-line, interactive, batch, etc.).
