// doexclusions.C
// ==============
//
// this macro sets the ExcludedFDA flag for runs, that can be excluded
// automatically
// the information which runs have to be excluded is retrieved from the
// resource file automatic-exclusions.rc
//
// the macro can be executed either for a night or for a range of runnumbers
// or for all nights
// .x doexclusions.C+("night", telnum)
// .x doexclusions.C+(startrun,stoprun, telnum)
// .x doexclusions.C+
//
// resource file: automatic-exclustions.rc
// for each exclusion-reason there is one block of 6 lines in this file:
// example for one exclusion-reason:
//  #NumEventsSmaller10:                   (name of exclusion)
//  key15.Column: fNumEvents               (name of the affected column)
//  #key15.Join1:                          (name of column that has to 
//  #key15.Join2:                                             be joined)
//  key15.Cond: fNumEvents between 2 and 9 (condition that fulfils exclusion)
//  #key15.SpecialRunCond:                 (special condition, if exclusion
//                                          is needed only for certain runs)
// if a value is not needed for an exclusion (like the joins and the special
// condition in this example), the line is commented out
//
// Returns 2 in case of failure, 1 in case of success and 0 if the connection
// to the database is not working.
