 Read INI data from a @var{port} and convert it to the Scheme representation.
 
+@var{log-driver} allows to set the logging driver. Possible values are:
+``syslog'' (used by default when @code{log-driver} is set to @code{#f}),
+``file'', ``null''.  Using @var{log-opt} parameter one can pass additional
+options for a logging driver.
