View source for Package usage

Even if Buildroot doesn't fully handle packages like debian/OpenEmbbeded and will probably never do ([http://lists.busybox.net/pipermail/buildroot/2011-November/047229.html]), you can still generate a package for your custom application and use it to update it on field, thanks to opkg.

==Install opkg on target==
<pre class="host">
$ make menuconfig
</pre>

<pre class="config">
Package Selection for the target  --->
    Package managers  --->
        [*] opkg
</pre>

<pre class="host">
$ make
</pre>
* reflash the rootfs on your APF

==Generate a package for your app==
* we assume that you already integrated your application in Buildroot and that ''buildroot/package/my_app/'' is existing.
* create a "control" file that will describe your application for opkg (''buildroot/package/my_app/opkg/control''):
<pre class="host">
Package: my-app
Version: 2.0.800
Description: My application
Section: applications
Priority: optional
Maintainer: Me
Architecture: arm
Homepage:
Source:
Depends:
</pre>
* add a new compile rule in ''buildroot/package/my_app/my_app.mk''
