+
+    <para><command>systemd-cat</command> may be used to connect the
+    standard input and output of a process to the journal, or as a
+    filter tool in a shell pipeline to pass the output the previous
+    pipeline element generates to the journal.</para>
+
+    <para>If no parameter is passed, <command>systemd-cat</command>
+    will write everything it reads from standard input (stdin) to the
+    journal.</para>
+
+    <para>If parameters are passed, they are executed as command line
+    with standard output (stdout) and standard error output (stderr)
+    connected to the journal, so that all it writes is stored in the
+    journal.</para>

+    <title>Options</title>
+
+    <para>The following options are understood:</para>

+        identify the logging tool. If not specified, no identification
+        string is written to the journal.</para></listitem>
+      </varlistentry>
+
+      <varlistentry>
+        <term><option>-p</option></term>
+        <term><option>--priority=</option></term>
+
+        <listitem><para>Specify the default priority level for the
+        logged messages. Pass one of
+        <literal>emerg</literal>,
+        <literal>alert</literal>,
+        <literal>crit</literal>,
+        <literal>err</literal>,

+        <literal>notice</literal>,
+        <literal>info</literal>,
+        <literal>debug</literal>, or a
+        value between 0 and 7 (corresponding to the same named
+        levels). These priority values are the same as defined by
+        <citerefentry project='man-pages'><refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
+        Defaults to <literal>info</literal>. Note that this simply
+        controls the default, individual lines may be logged with
+        different levels if they are prefixed accordingly. For details,
+        see <option>--level-prefix=</option> below.</para></listitem>
+      </varlistentry>
+
+      <varlistentry>
+        <term><option>--stderr-priority=</option></term>
+
+        <listitem><para>Specifies the default priority level for
+        messages from the process's standard error output (stderr).
+        Usage of this option is the same as the
+        <option>--priority=</option> option, above, and both can be
+        used at once. When both are used, <option>--priority=</option>
+        will specify the default priority for standard output (stdout).
+        </para>
+
+        <para>If <option>--stderr-priority=</option> is not specified,
+        messages from stderr will still be logged, with the same
+        default priority level as stdout.</para>
+
+        <para>Also, note that when stdout and stderr use the same
+        default priority, the messages will be strictly ordered,
+        because one channel is used for both. When the default priority
+        differs, two channels are used, and so stdout messages will not
+        be strictly ordered with respect to stderr messages - though
+        they will tend to be approximately ordered.</para>

+
+        <listitem><para>Controls whether lines read are parsed for syslog priority level prefixes. If enabled
+        (the default), a line prefixed with a priority prefix such as <literal>&lt;5&gt;</literal> is logged
+        at priority 5 (<literal>notice</literal>), and similarly for the other priority levels. Takes a

+    <title>Examples</title>
+
+    <example>
+      <title>Invoke a program</title>
+
+      <para>This calls <filename index="false">/bin/ls</filename>
+      with standard output and error connected to the journal:</para>
+
+      <programlisting># systemd-cat ls</programlisting>
+    </example>
+
+    <example>
+      <title>Usage in a shell pipeline</title>
+
+      <para>This builds a shell pipeline also invoking
+      <filename>/bin/ls</filename> and writes the output it generates
+      to the journal:</para>
+
+      <programlisting># ls | systemd-cat</programlisting>
+    </example>
+
+    <para>Even though the two examples have very similar effects, the first is preferable, since only one
+    process is running at a time and both stdout and stderr are captured, while in the second example, only
+    stdout is captured.</para>
