+// buildsequenceentries.C
+// ======================
+//
+// to group the runs of one night into sequences, this marco:
+//  - reads the runinformation of one night from the database
+//  - group the runs into sets of following runs with the same conditions
+//  - groups the runs in this sets to sequences such that each run belongs
+//    to the nearest (in time) calibration run
+//  - check if the runs with the same runtype have the same calibration script
+//    and the same trigger tables
+//  if sequence is okay:
+//  - check if in the range of the runnumbers of this sequence other sequences
+//    exist in the database
+//  if there are no sequences, insert the new sequence, else:
+//  - delete overlaping sequences
+//  if there's only one sequence in the same runnumber range:
+//  - check if the new and the old sequence are identical
+//    if they are identical, do nothing, if not, delete the old sequence and
+//    insert the new one
+//
+// remark: deleting sequences includes the following steps:
+// - delete entries from the tables Sequences, SequenceProcessStatus,
+//   Calibration and Star
+// - updating the sequence number (fSequenceFirst) in the table RunData
+// - remove the Sequence File, the calibrated data and the image files from
+//   the disk
+//
+// the macro can be executed either for all nights or for one single night
+// .x buildsequenceentries.C+( "datapath", "sequpath", Bool_t dummy=kTRUE)
+// .x buildsequenceentries.C+( "night", "datapath", "sequpath")
+//
+// the Bool_t dummy:
+//  kTRUE:  dummy-mode, i.e. nothing is inserted into the database, but the
+//          commands, that would be executed are returned
+//  kFALSE: the information is inserted into the database and the files of
+//          removed sequences is deleted
+// be careful with this option - for tests use always kTRUE
+//
+// TString datapath, TString sequpath:
+//  datapath: path, where the processed data is stored in the datacenter
+//  sequpath: path, where the sequence files are stored in the datacenter
+// the datapath (standard: /magic/data/) and the sequencepath (standard:
+// /magic/sequences) have to be given, that the sequence file, the
+// calibrated data and the star files can be removed, when an old sequence
+// has to be removed from the database
+//
+// If nothing failes 1 is returned. In the case of an error 2 and if
+// there's no connection to the database 0 is returned.
+// This is needed for the scripts that execute the macro.
