-// FindCaCoFiles.C
+// findcacofiles.C
 // ===============
+//
+// Macro to get from the database the number of the runs, for which no caco
+// file is available.
+//
+// Sometimes the DAQ aborts a run and starts itself a new one. In this cases
+// there's 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.
+// findcacofiles.C produces the input for this script. It queries from the
+// database, for which runs no caco file with the same runnumber is available
+// and writes the runnumbers into an txt file.
+//
+// Usage:
+//   .x findcacofiles.C+("date", "logpath")
+// date and logpath are needed only for the output file
+//
+// 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.
