Creating your own board support</h3>
<p>Once a package has been unpacked, it is possible to manually update
configuration files. Buildroot can automatically save the configuration
of buildroot, linux, busybox, uclibc and u-boot in "local/$(PROJECT) by
using the command:
</p>
<pre>
$ make saveconfig
</pre>
<p>Once a buildroot configuration has been created by saveconfig,
the default "$(TOPDIR)/.config" file can be overridden by</p>
<pre>
$ make BOARD=&lt;project&gt;
</pre>
<p>Buildroot will then use "local/&lt;project&gt;/&lt;project&gt;.config"
instead of ".config". </p>
<p>If you want to modify your board, you can copy the project configuration
file to ".config" by using the command:</p>
<pre>
$ make BOARD=&lt;project&gt; getconfig
</pre>
<p>You can share your custom board support directory between several buildroot trees
by setting the environment variable <code>BUILDROOT_LOCAL</code> to this directory,

Offline builds</h3>
<p>If you intend to do an offline-build and just want to download all
sources that you previously selected in &quot;make menuconfig&quot; then
