Configuration file and command line

In all these programs a module is used which can handle the combination of command line and configuration file usage. Because in all programs always the same module is used, this description is valid for all of them. Nevertheless, there are some programs which support both interfaces (like storeBackup.pl) and others which support only command line (like storeBackupMount.pl). In general, programs which support a complex configuration have both interfaces, while the ones with a more simple configuration only support command line.
