+not only the validation is requested, then the provided archive file will be
+placed in the incoming area of the CTAN for further processing by the CTAN
+team.  In any case any finding during the validation is reported at the end of
+the processing.  Note that the validation is the default and an official
+submission has to be requested by an appropriate command line option.")
