-       <title>DESCRIPTION</title>
-       <para>
-       <command>asterisk</command> is a full-featured telephony server which
-       provides Private Branch eXchange (PBX), Interactive Voice Response (IVR),
-       Automated Call Distribution (ACD), Voice over IP (VoIP) gatewaying, 
-       Conferencing, and a plethora of other telephony applications to a broad
-       range of telephony devices including packet voice (SIP, IAX2, MGCP, Skinny,
-       H.323, Unistim) devices (both endpoints and proxies), as well as traditional TDM
-       hardware including T1, E1, ISDN PRI, GR-303, RBS, Loopstart, Groundstart,
-       ISDN BRI and many more.
-       </para>
-       <para>
-       At start, Asterisk reads the /etc/asterisk/asterisk.conf main configuration
-       file and locates the rest of the configuration files from the configuration
-       in that file. The -C option specifies an alternate main configuration file.
-       Virtually all aspects of the operation of asterisk's configuration files
-       can be found in the sample configuration files.  The format for those files
-       is generally beyond the scope of this man page.
-       </para>
-       <para>
-       When running with <command>-c</command>, <command>-r</command> or <command>-R</command>
-       options, Asterisk supplies a powerful command line, including command
-       completion, which may be used to monitors its status, perform a variety
-       of administrative actions and even explore the applications that are
-       currently loaded into the system.

+  <title>DESCRIPTION</title>
+  <para>
+   <command>asterisk</command> is a full-featured telephony server which
+   provides Private Branch eXchange (PBX), Interactive Voice Response (IVR),
+   Automated Call Distribution (ACD), Voice over IP (VoIP) gatewaying, 
+   Conferencing, and a plethora of other telephony applications to a broad
+   range of telephony devices including packet voice (SIP, IAX2, MGCP, Skinny,
+   H.323, Unistim) devices (both endpoints and proxies), as well as traditional TDM
+   hardware including T1, E1, ISDN PRI, GR-303, RBS, Loopstart, Groundstart,
+   ISDN BRI and many more.
+  </para>
+  <para>
+   At start, Asterisk reads the /etc/asterisk/asterisk.conf main configuration
+   file and locates the rest of the configuration files from the configuration
+   in that file. The -C option specifies an alternate main configuration file.
+   Virtually all aspects of the operation of asterisk's configuration files
+   can be found in the sample configuration files.  The format for those files
+   is generally beyond the scope of this man page.
+  </para>
+  <para>
+   When running with <command>-c</command>, <command>-r</command> or <command>-R</command>
+   options, Asterisk supplies a powerful command line, including command
+   completion, which may be used to monitors its status, perform a variety
+   of administrative actions and even explore the applications that are
+   currently loaded into the system.

+  <para>
+   Running Asterisk starts the asterisk daemon (optionally running it
+   in the foreground). However running it with <option>-r</option> or
+   <option>-R</option> connects to an existing Asterisk instance through
+   a remote console.
