[ef13657]34<para>For years it has been common practice to use <quote>raw</quote>
35kernel headers (straight from a kernel tarball) in <filename
36class="directory">/usr/include</filename>, but over the last few
37years, the kernel developers have taken a strong stance that this
[69993f4]38should not be done. This gave birth to the Linux-Libc-Headers Project,
[ef13657]39which was designed to maintain an API stable version of the Linux
40headers.</para>
