// insertcacofiles.C
// =================
//
// Macro to insert runnumber of the caco files, which contain the information
// for a run, for which no caco file is available.
//
// Sometimes the DAQ aborts a run and starts itself a new one. In this cases
// the camera controll doesn't start a new file, as the command to
// start a new run was not sent by the central control. So the caco
// information is stored in the previous caco file, which has a different
// runnumber. To be able to merpp the information into the calibrated data
// file, the runnumber of the file containing the information has to be found.
// This is done by a script.
// insertcacofiles.C inserts the runnumber of the file, that has been found,
// into the column CaCoFileFound. 
//
// Usage:
//   .x insertcacofile.C+("runnumber", "newrunnumber")
// The first is the runnumber of which the cacofile is missing, the second is
// the runnumber of the file in which the information probably can be found.
//
// Make sure, that database and password are corretly set in a resource
// file called sql.rc and the resource file is found.
//
// Returns 0 in case of failure and 1 in case of success.
