However, since some programs (including the RCS revision control system)
use C<LOGNAME> to determine the real identity of the user, it may be desirable
to change this behavior. This can be done by negating the set_logname option.
-However, unless the I<env_reset> option has been disabled it is generally
-better to add C<LOGNAME> and C<USER> to the I<env_keep> list instead.
+Note that if the I<env_reset> option has not been disabled, entries in
+the I<env_keep> list will override the value of I<set_logname>.
