+.B -N\fIpath\fP
+This is used for debugging the compiler proper. Dump the final netlist
+form of the design to the specified file. It otherwise does not affect
+operation of the compiler. The dump happens after the design is
+elaborated and optimized.

 .B -o \fIfilename\fP
 Place output in the file \fIfilename\fP. If no output file name is
 specified, \fIiverilog\fP uses the default name \fBa.out\fP.
