296 Once the ``.config`` file has everything needed, all it takes to build
311 some ways to build just the new drivers, using alternative trees.
325 it would work (or even build) on a random Kernel. This tree is maintained
326 using a "best-efforts" principle, as time permits us to fix issues there.
330 add ``[PATCH media-build]`` at the e-mail's subject if you submit a new
331 patch for the media-build.
335     $ ./build
339     1) you may need to run it twice if the ``media-build`` tree gets
344     3) by default, it will use the same config options for media as
