Readability fixes:
Clearly comment the assumptions on the structure of keys (addresses) and masks, and introduce a macro, LEN(p), to extract the size of these objects instead of using *(u_char *)p which might be confusing. Comment the confusion in the types used to pass around pointers to keys and masks, as a reminder to fix that at some point. Add a few comments on what some functions do. Comment a probably inefficient (but still correct) section of code in rn_walktree_from() The object code generated after this commit is the same as before. At some point we should also change same variable identifiers such as "t, tt, ttt" to fancier names such as "root, left, right" (just in case someone wants to understand the code!), replace misspelling of NULL as 0, remove 'register' declarations that make little sense these days.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
