TotemRawDataLibrary is a code package for reading and validating TOTEM raw data. It provides an abstraction layer to provide unified access to data irrespectively of their format or storage location (local disk, CASTOR, EOS, ...).
Conception
Strictly speaking, this package is not a library, but a piece of code that is shared between Monitor and OfflineSW. This implies a specific
organisation in the SVN repository.

| @host1@host2: |
