=head1 DESCRIPTION
The C<exec plugin> forks of an executable either to receive values, to dispatch
-notifications to the outside world or to be able to use Nagios plugins.
+notifications to the outside world or to be able to use Nagios plugins. The
+syntax of the configuration is explained in L<collectd.conf(5)> but summarized
+in the above synopsis.
If you want/need better performance or more functionality you should take a
long look at the C<perl plugin>, L<collectd-perl(5)>.

Execute the executable I<Executable> as user I<User>. If the user name is
followed by a colon and a group name, the effective group is set to that group.
specify the same user/group here. If the daemon is run with superuser
privileges, you must supply a non-root user here.
+The executable may be followed by optional arguments that are passed to the
+program. Please note that due to the configuration parsing numbers and boolean
+values may be changed. If you want to be absolutely sure that something is
+passed as-is please enclose it in quotes.
+
+The B<Exec>, B<NotificationExec>, and B<NagiosExec> statements change the
+semantics of the programs executed, i.E<nbsp>e. the data passed to them and the
+response expected from them. This is documented in great detail in
+L<collectd-exec(5)>.
