164
normally written to /etc/mandos for later installation into the

initrd image, but this, and most other things, can be changed
172
with command line options.
175
This program can also be used with the
176
<option>--password</option> or <option>--passfile</option>
177
options to generate a ready-made section for
178
<filename>clients.conf</filename> (see

command line options.
