// fillcalib.C
// ===========
//
// This macro is used to read the calibartion-/callisto-output files.
// These files are automatically called calib00000.root.
//
// From this file the MBadPixelsCam and the MGeomCam is extracted. If
// the geometry isn't found MGeomCamMagic is used as a default.
// The bad pixel information and other information, extracted from the status
// display, is inserted into the database in the table Calibration, which
// stores the results from the calibration.
// The corresponding sequence number is extracted from the filename...
// FIXME: MSeqeuence should be stored in the calib-file?
//
// Usage:
//  .x fillcalib.C("/magic/data/callisto/0004/00047421/calib00047421.root", kTRUE)
//
// 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.
//
// 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 fillcalib.C+\(\"filename\"\,kFALSE\) 2>&1 | tee fillcalib.log
//
// Make sure, that database and password are corretly set in a resource
// file called sql.rc and the resource file is found.
//
// Returns 2 in case of failure, 1 in case of success and 0 if the connection
// to the database is not working.
