// checkfileavail.C
// ================
//
// check the availability of the files of one sequence:
// the script filesondisk has inserted the information (which files are on
// disk into the database) and with this macro this information is checked
// for the runs of one sequence
//
// executing the macro:
//  .x checkfileavail.C+(100002)
// the sequencefile (including path) has to be given, as the macro retrieves
// from there the runnumbers
//
// the macro returns 0, if there's no connection to the database, 2 if a
// file is missing, and 1 if all files are there, 3 in case of error.
// the return value is checked by the script, that executes the macro
//
// this macro is very similar to the macro checkstardone.C
//
