	<question id="ports-update">

	  <para>I updated the sources, now how do I update my installed ports?</para>

	</question>

	<answer>

	  <para>Unfortunately, there is no easy way to udpate

	  installed ports. The <command>pkg_version(1)</command>

	  command can be used to generate a script that will update

	  the installed ports with a newer version in the ports

	  tree:</para>

	  <screen>&prompt.root; <userinput>pkg_version <option>-c</option> > <replaceable>/tmp/myscript</replaceable></userinput></screen>

	  <para>The output script <emphasis>must</emphasis> be edited

	    by hand before you use it. Current versions of

	    <command>pkg_version</command> force this by inserting an

	    <command>exit</command> at the beginning of the script.</para>

	  <para>You should save the output of the script, as it will

	     note packages that depend on the one that has been

	     udpated. These may or may not need to be updated as

	     well. The usual case where they need to be updated is

	     that a shared library has changed version numbers, so the

	     ports that used that library need to be rebuilt to use

	     the new version.</para>

	   <para>If your system is up full time, the &man.periodic.8

	     system can be used to generate a weekly list of ports that

	     might need updating by setting

	     <literal>weekly_status_pkg_enable="YES"</literal> in

	     <filename>/etc/periodic.conf</filename>.</para>
