    <para os="a">For years it has been common practice to use
    <quote>raw</quote> kernel headers (straight from a kernel tarball) in
    <filename class="directory">/usr/include</filename>, but over the last few
    years, the kernel developers have taken a strong stance that this
    should not be done. This gave birth to the Linux-Libc-Headers Project,
    which was designed to maintain an API stable version of the Linux
    headers. Recently this project stopped producing updates, so the Cross-LFS
    team started development on our own project to sanitize the headers.</para>
