// fillganymed.C
// =============
//
// This macro is used to read the ganymed-output files.
// These files are automatically called ganymed00000.root.
// From MAlphaFitter and the Status Display the results from ganymed are
// extracted an inserted into the database, where they are stored in the table
// Ganymed.
// The dataset number is extracted from the filename.
//
// Usage:
//  .x fillganymed.C("/magic/data/ganymed/0000/0001/ganmymed0001.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.
//
// Remark: Running it from the commandline looks like this:
//   root -q -l -b fillganymed.C+\(\"filename\"\,kFALSE\) 2>&1 | tee file.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.
