- </p><div class="refsection" title="Overlay lists"><a name="layman-remote"></a><h3>Overlay lists</h3><p><span class="command"><strong>layman</strong></span> allows you to fetch an
- overlay without the need to modify any configuration
- files. In order for this to be possible the script needs an
- external list of possible overlay sources. There is a
- centralized list available at <a class="ulink" href="http://www.gentoo.org/proj/en/overlays/repositories.xml" target="_top">http://www.gentoo.org/proj/en/overlays/repositories.xml</a>
- but nothing will prevent you from using or publishing your
- own list of overlays. The location of the remote lists can
- also be modified using the <code class="option">--overlays</code>
- option when running <span class="command"><strong>layman</strong></span>.
- </p><p>To get a new overlay added to the central list provided
- for layman, send a mail to
- <code class="email">&lt;<a class="email" href="mailto:overlays@gentoo.org">overlays@gentoo.org</a>&gt;</code>. Gentoo developers may
- add their overlay entries directly into the list which can
- be accessed over the CVS repository for the Gentoo
- website.
- </p><p>You can also use several lists at the same time. Just
- add one URL per line to the overlays variable in your
- configuration file. <span class="command"><strong>layman</strong></span> will merge the
- contents of all lists.
- </p><p><span class="command"><strong>layman</strong></span> also allows you to define
- local files in this list. Just make sure you prepend these
- path names in standard URL notation
- with <code class="filename">file://</code>.
- </p><p>If you need to use a proxy for access to the Internet,
- you can use the corresponding variable in
- the <span class="command"><strong>layman</strong></span> configuration file. Layman
- will also respect the <span class="command"><strong>http_proxy</strong></span>
- environment variable in case you set it.
- </p></div><div class="refsection" title="Local cache"><a name="layman-local"></a><h3>Local cache</h3><p><span class="command"><strong>layman</strong></span> stores a local copy of the

- </p></div><div class="refsection" title="Handling /etc/make.conf"><a name="layman-make-conf"></a><h3>Handling <code class="filename">/etc/make.conf</code></h3><p>Since <span class="command"><strong>layman</strong></span> is designed to
- automatically handle the inclusion of overlays into your
- system it needs to be able to modify
- the <span class="command"><strong>PORTDIR_OVERLAY</strong></span> variable in your
- <code class="filename">/etc/make.conf</code> file. But
- <code class="filename">/etc/make.conf</code> is a very central and
- essential configuration file for a Gentoo
- system. Automatically modifying this file would be
- somewhat dangerous. You can
- allow <span class="command"><strong>layman</strong></span> to do this by setting
- the <span class="command"><strong>make_conf</strong></span> variable in the
- configuration file to <code class="filename">/etc/make.conf</code>.
- </p><p>A much safer and in fact recommended solution to the
- problem is to let <span class="command"><strong>layman</strong></span> handle an
- external file that only contains
- the <span class="command"><strong>PORTDIR_OVERLAY</strong></span> variable and is
- sourced within the
- standard <code class="filename">/etc/make.conf</code> file. Just add the following line to the end of your
- <code class="filename">/etc/make.conf</code> file:
- </p><p>source /var/lib/layman/make.conf</p><p><code class="filename">/var/lib/layman/make.conf</code>
- is the default provided in the layman
- configuration. Change this file name in case you decide to
- store it somewhere else.
- </p><p>The file does not necessarily need to exist at the
- beginning. If it is missing, layman will create it for you.
- </p><p>There is also no need to remove the
- original <span class="command"><strong>PORTDIR_OVERLAY</strong></span> variable from
- the make.conf file. Layman will simply add new overlays to
- this variable and all your old entries will remain in there.
- </p></div><div class="refsection" title="Adding, removing and updating overlays"><a name="layman-update"></a><h3>Adding, removing and updating overlays</h3><p>Once a remote list of overlays has been fetched,

- <span class="command"><strong>layman</strong></span> will modify the

- new overlay path.
- </p><p>Removing the overlay with <span class="command"><strong>layman</strong></span> will
- delete the overlay without leaving any traces behind.
- </p><p>In order to update all overlays managed by

- with a green asterisk, all non-official overlays with a

- </p><p> In the default mode layman will be strict about

- Simply create an overlay list in the format described
- above and run <span class="command"><strong>layman</strong></span> with the
- <code class="option">-o</code> switch. You need to
- prepend local file URLs with
- <strong class="userinput"><code>file://</code></strong>.
- </p></div><div class="refsection" title="Adding an overlay globally"><a name="id3030868"></a><h3>Adding an overlay globally</h3><p>
- The global list of overlays used by
- <span class="command"><strong>layman</strong></span> lies at
- <code class="filename">http://www.gentoo.org/proj/en/overlays/repositories.xml</code>.
- </p><p>
- All Gentoo developers have access to this location via CVS
- and can modify the list of overlays.
- </p><p>
- If you are not a Gentoo developer but wish to get your
- overlay listed you should contact the Gentoo Overlays team
- at <code class="email">&lt;<a class="email" href="mailto:overlays@gentoo.org">overlays@gentoo.org</a>&gt;</code>. You can also join
