=head1 DESCRIPTION
a file or files containing random data used to seed the random number
generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>).
Multiple files can be specified separated by a OS-dependent character.

+The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
all others.
=item I<numbits>
this option converts the parameters into C code. The parameters can then
be loaded by calling the B<get_dh>I<numbits>B<()> function.
+=item B<-engine id>
+
+specifying an engine (by its unique B<id> string) will cause B<dhparam>
+to attempt to obtain a functional reference to the specified engine,
+thus initialising it if needed. The engine will then be set as the default
+for all available algorithms.
