+.SH EXTENDED ARGUMENTS
+.PP
+The vvp options described above must come before the design file name.
+After the design file name, however, there may be any number of
+unspecified arguments. These arguments are not interpreted by vvp but
+are instead passed on to the executed design, and are available via
+the \fI$test$plusargs\fP and \fI$value$plusargs\fP system functions.
+.PP
+Arguments that do not start with the plus(+) character are not
+available to the standard system tasks, but can still be accessed via
+PLI code via the \fIvpi_get_vlog_info\fP function. This means that
+vpi modules may use arguments that do not start with + and be assured
+that they do not interfere with user defined plus-args.
