 // ================
 //
+// 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+("sequencefile")
+// the sequencefile (including path) has to be given, as the macro retrieves
+// from there the runnumbers
+//
+// the macro returns 0, if a file is missing, and 1 if all files are there
+// the return value is checked by the script, that executes the macro
+//
+// this macro is very similar to the macro checkstardone.C
