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 specifies that a parameter set should be generated of size
-I<numbits>. It must be the last option. If not present then a value of 512
-is used. If this option is present then the input file is ignored and
-parameters are generated instead.
