AddFlags registers this package's flags on arbitrary FlagSets, such that they point to the same value as the global flags.

PrintDefaultConfigAndExitIfRequested will check if the --defaultconfig flag was passed and, if so, print the default config and exit.

PrintFlags logs the flags in the flagset.

PrintMinConfigAndExitIfRequested will check if the -minconfig flag was passed and, if so, print the min config and exit.
