// fillstar.C
// ==========
//
// This macro is used to read the star-output files.
// These files are automatically called star00000000.root.
// From these files the muon parameters (psf, muon number, ratio, muon rate),
// the  rate, the number of islands, the effective ontime, the maximum
// humidity and a parameter describing the inhomogeneity are extracted from
// the status display.
// The sequence number is extracted from the filename.
//
// Usage:
//   .x fillstar.C("/magic/data/star/0004/00047421/star00047421.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 fillstar.C+\(\"filename\"\,kFALSE\) 2>&1 | tee fillstar.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.
