<span style="color:black">To start this process, we have collected a small number of core features that we would propose to add to the OpenWrt build system. Our goal with these patches is to remove the need for companies to develop external scripts used to
manipulate the build configuration of OpenWrt. We will present the use cases and our proposed way to implement these in a series of emails.<o:p></o:p></span></p>
