+define Package/wdctl/description
+ Show hardware watchdog status. The default device is /dev/watchdog. If more
+ than one device is specified then the output is separated by one blank line.
+ If the device is already used or user has no permissions to read from the
+ device, then wdctl reads data from sysfs. In this case information about
+ supported features (flags) might be missing. Note that the number of supported
+ watchdog features is hardware specific.
