 +Kernel API documentation
 +------------------------
 +
 +These books get into the details of how specific kernel subsystems work
 +from the point of view of a kernel developer.  Much of the information here
 +is taken directly from the kernel source, with supplemental material added
 +as needed (or at least as we managed to add it — probably *not* all that is
 +needed).
