I suggest the following ordering and content:

- The build system is much improved compared to 2.4.
You should notice quicker builds, and no spontaneous rebuilds of files
on subsequent builds from already built trees.
- There are two new graphical config tools.
"make xconfig" requires the qt libraries.
"make gconfig" requires gtk libraries.
- Make menuconfig/oldconfig has no user-visible changes other than speed,
whilst numerous improvements have been made.
- 'make help' provides a list of typical targets, including several new
debugging targets ('allyesconfig' 'allnoconfig' 'allmodconfig' + more).
- "make" is now the preferred command, without a target; it builds
<arch-zimage> and modules. See 'make help' for what is built by default.
- "make -jN" is now the preferred parallel-make execution.
Do not bother to provide "MAKE=xxx"
- Output files can be directed to an alternative directory. Use 'make O=dir'
to locate all output files (including .config) in 'dir'.
- The build is now much less verbose. If you want to see exactly what's
going on, try "make V=1" or set KBUILD_VERBOSE=1 in your environment.
- 'make kernel/mm.o' will build the named file, provided a
corresponding source exists. This also works for (non-composite)
- 'make kernel/' will recursively build all files in the specified
subdirectory and below.
- 'make dep' has been obsoleted and does no longer have any effect.
- Note: The new configuration system is not CML2 related.
- Also note: Whilst some ideas were taken from it, Keith Owens'
kbuild-2.5 project was not integrated.
