func Populate(set *flag.FlagSet, prefix string) error

Populate sets the flags in set from the environment. The environment value used will be the name of the flag in upper case, with '-' changed to '_', and (if prefixis not the empty string) prepended with prefix and an underscore. So, if prefix is "DOORMAN", and the flag's name "foo-bar", the environment variable DOORMAN_FOO_BAR will be used.
