-The configuration parameters for @command{comsatd} are kept in a single
-configuration file. The file uses line-oriented format: each line
-contains a single statement. Comments are introduced with the @samp{#}
-sign and empty lines are ignored. You can specify the configuration
-file to use by using @option{-c} or @option{--config} command line switch.
+Following configuration statements affect the behavior of
+@command{comsatd}:
 
-The configuration file statements can logically be subdivided into
-@dfn{General Settings}, @dfn{Security Settings} and @dfn{Access Control
-Lists}. The following sections address each of these statement group in

 These statements control the way @command{comsatd} fights possible
 flooding attacks.
 
-@table @asis
-@item max-requests @var{number}
-Set maximum number of incoming requests per @samp{request-control-interval}.
-@item request-control-interval @var{number}
-Set the request control interval (seconds).
-@item overflow-delay-time @var{number}
-Set the initial amount of time to sleep, after the first overflow occurs.
-@item overflow-control-interval @var{number}
-Set the overflow control interval. If two consecutive overflows happen
-within @var{number} seconds, the overflow-delay-time is doubled.

-
-@node Access Control Lists
-@subsubheading Access Control Lists
-
-Access control lists determine from which addresses @command{comsatd}
-will receive mail notification messages.
-
-The access control lists are introduced in configuration file using
-keyword @samp{acl}. General format for an ACL rule is
-
-@smallexample
-acl @var{action} @var{netlist}
-@end smallexample
-
-@noindent
-Here, @var{action} specifies the action to be taken when a request
-arrives from one of the networks, listed in @var{netlist}. There are
-two possible actions: @samp{allow} and @samp{deny}.
-
-The @var{netlist} is a whitespace-separated list of network numbers.
-Each network number may be specified in one of the following forms:
-
-@table @asis
-@item @var{netnum}
-Means a single host with IP address @var{netnum}.
-@item @var{netnum}/@var{netmask}
-@item @var{netnum}/@var{masklen}
-@item @samp{any}
-Denotes any IP address. It is equivalent to @samp{0.0.0.0/0}.
-@end table
-
-Upon receiving a notification message, @command{comsatd} compares its
-source address against each ACL rule in the order of their appearance
-in the configuration file. The first rule that matches the packet
-determines whether the message will be processed or rejected. If
-no matching rule was found, the default rule applies. Currently, default
-rule is
-
-@smallexample
-acl allow any
-@end smallexample
+@deffn {Comsatd Conf} max-requests @var{number}
+Set maximum number of incoming requests per
+@samp{request-control-interval}.
+@end deffn
 
-@noindent
-If you don't need such behavior, specify the default rule explicitly.
-For example, the common use would be:
+@deffn {Comsatd Conf} request-control-interval @var{duration}
+Set the request control interval.
+@end deffn

-@group

+@deffn {Comsatd Conf} overflow-delay-time @var{duration}
+Set initial amount of time to sleep, after the first overflow occurs.
+@end deffn
 
-@noindent
-which makes @command{comsatd} receive the notification messages from
-localhost only.
+@deffn {Comsatd Conf} overflow-control-interval @var{duration}
+Set overflow control interval. If two consecutive overflows happen
+within that interval, the overflow-delay-time is doubled.
