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

initrd image, but this, and most other things, can be changed
174
with command line options.
177
This program can also be used with the
178
<option>--password</option> or <option>--passfile</option>
179
options to generate a ready-made section for
180
<filename>clients.conf</filename> (see
