+Furter developement on the Shuttle:
+
+- Shuttle now connects to the Grid as alidaq. The OCDB and Reference folders
+are now built from /alice/data, e.g.:
+/alice/data/2007/LHC07a/OCDB
+
+the year and LHC period are taken from the Shuttle.
+Raw metadata files are stored by GRP to:
+/alice/data/2007/LHC07a/<runNb>/Raw/RunMetadata.root
+
+- Shuttle sends a mail to DCS experts each time DP retrieval fails.
+
 Revision 1.61  2007/10/30 20:33:51  acolla
