//
// fillcmt.C
// =========
//
// This macro is used to read an extinction file from the CMT and fill
// its contents into the db.
//
// Usage:
//   .x fillcmt.C("camext.06", 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.
//
// Filling the database is done with 'UPADTE' for _all_ columns
// matching the date!
//
// 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 fillcmt.C+\(\"filename\"\,kFALSE\) 2>&1 | tee fillcmt.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.
//
