<title>Description</title>
<para>&kdesu; is a graphical front end for the
&UNIX; <command>su</command> command for the K Desktop Environment.
It allows you to run a program as different user by supplying the
password for that user. &kdesu; is an unprivileged program; it uses
the system's <command>su</command>.</para>

<para>&kdesu; has one additional feature: it can optionally remember passwords
for you. If you are using this feature, you only need to enter the
password once for each command.</para>

<para>This program is meant to be started from the command line or
from <filename>.desktop</filename> files.</para>

<para>Since <command>kdesu</command> is no longer installed in <userinput>
$(kde4-config --prefix)</userinput>/bin but in <userinput>kde4-config --path libexec</userinput> 
and therefore not in your <envar>Path</envar>, you have to use <userinput>$(kde4-config 
--path libexec)<command>kdesu</command></userinput> to launch <command>kdesu</command>.</para>

<variablelist>
<varlistentry>
<term><option>-c <replaceable>command</replaceable></option></term>
<listitem><para>This specifies the command to run as root. It has to be passed
in one argument. So if, for example, you want to start a new file manager, you
would enter at the prompt: <userinput>$(kde4-config --path libexec)<command>kdesu <option>-c <replaceable>
&dolphin;</replaceable></option></command></userinput></para></listitem>

<varlistentry>
<term><option>-d</option></term>
<listitem><para>Show debug information.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>-f <replaceable>file</replaceable></option></term>
<listitem><para>This option allow efficient use of &kdesu; in
<filename>.desktop</filename> files. It tells &kdesu; to examine the
file specified by <parameter>file</parameter>. If this file is
writable by the current user, &kdesu; will execute the command as the
current user. If it is not writable, the command is executed as user
<parameter>user</parameter> (defaults to root).</para>
<para><parameter>file</parameter> is evaluated like this: if
<parameter>file</parameter> starts with a <literal>/</literal>, it is
taken as an absolute filename. Otherwise, it is taken as the name of a
global &kde; configuration file.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>-i</option> <replaceable>icon name</replaceable></term>
<listitem><para>Specify icon to use in the password dialog.  You may specify
just the name, without any extension.</para>

<listitem><para>Do not keep the password. This disables the <guilabel>keep
password</guilabel> checkbox in the password dialog.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>-p</option> <replaceable>priority</replaceable></term>
<listitem>
<para>Set priority value.  The priority is an arbitrary number between 0 and

<option>-n</option> when &kdesu; is initially run.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>-t</option></term>

<term><option>-u</option> <replaceable> user</replaceable></term>
