//
// filldotrbk.C
// ============
//
// This macro is used to read the central control runbook files from
// the data center and store their contents in the runbook-database.
//
// Usage:
//   .x filldotrbk.C("/data/MAGIC/Period014", kTRUE)
//
// While the first argument is the directory in which all subdirectories where
// searches for CC_*.rbk files. All these files were analysed and the runbook
// entries will be put into the DB, eg:
//   "/data/MAGIC"                              would do it for all data
//   "/data/MAGIC/Period019/ccdata"             would do it for one Period
//   "/data/MAGIC/Period019/ccdata/2004_05_17"  would do it for a single day
//   "/data/MAGIC/Period019/ccdata/file.rbk"    would do it for a single file
//
// The second argument is the 'dummy-mode'. If it is kTRUE dummy-mode is
// switched on and nothing will be written into the database. This is usefull
// for tests.
//
// Before an antry is added its existance is checked... if it is added already
// it is ignored.
//
// The macro can also be run without ACLiC but this is a lot slower...
//
// Remark: Running it from the commandline looks like this:
//   root -q -l -b filldotrbk.C+\(\"path\"\,kFALSE\) 2>&1 | tee filldotrbk.log
//
// Make sure, that database and password are corretly set in the macro.
//
// Returns 0 in case of failure and 1 in case of success.
