++.B execute (\fIcommand-path\fB, \fIdata-expr1\fB ... \fIdata-exprN\fB)\fR
++.PP
++External command execution is possibly through execute expressions. Execute
++takes a variable number of arguments, where the first is the command
++name (full path or only the name of the executable) and following zero
++or more are data-expressions which values will be passed as external
++arguments. It returns the return code of the external command.
++.PP
++Execute is synchronous, and the program will block until the external
++command being run has finished. Please note that lengthy program
++execution (for example, in an "on commit" in the dhcpd) may result in
++bad performance and timed out clients. Try keeping the execution times
++short.
++.PP
++Passing user-supplied data might be dangerous. Check input buffers
++and make sure the external command handles all kinds of "unusual"
++characters (shell special characters in sh-scripts etc) correctly.
++.PP
++It is possible to use the execute expression in any context, not only
++on events. If you put it in a regular scope in the configuration file
++you will execute that command every time a scope is evaluated.
++.PP
++The execute expression is only available if you have defined ENABLE_EXECUTE
++in site.h before compilation.
