<title>DESCRIPTION</title>
<para>
This program reads a password from a <acronym>FIFO</acronym> and
outputs it to standard output.
</para>
<para>
This program is not very useful on its own. This program is
really meant to run as a plugin in the <application
>Mandos</application> client-side system, where it is used as a
fallback and alternative to retrieving passwords from a
<application >Mandos</application> server.
</para>
<para>
This program is meant to be imitate a feature of the
<command>askpass</command> program, so that programs written to
interface with it can keep working under the
<application>Mandos</application> system.
</para>
</refsect1>
<refsect1 id="options">
<title>OPTIONS</title>
<para>
This program takes no options.
</para>
</refsect1>
<refsect1 id="exit_status">
<title>EXIT STATUS</title>
<para>
If exit status is 0, the output from the program is the password
as it was read. Otherwise, if exit status is other than 0, the
program was interrupted or encountered an error, and any output
so far could be corrupt and/or truncated, and should therefore
be ignored.

This is the <acronym>FIFO</acronym> where this program

created.

Note that normally, this program will not be invoked directly,

<title>SECURITY</title>
<para>
The only thing that could be considered worthy of note is
this: This program is meant to be run by <citerefentry>
<refentrytitle>plugin-runner</refentrytitle><manvolnum
>8mandos</manvolnum></citerefentry>, and will, when run
standalone, outside, in a normal environment, immediately output
on its standard output any presumably secret password it just
received. Therefore, when running this program standalone
(which should never normally be done), take care not to type in
any real secret password by force of habit, since it would then
immediately be shown as output.
