The Makefile in this directory supports a number of targets forbuilding components (or all) of the FreeBSD source tree.  

See build(7)and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html

for more information, including setting make(1) variables.The `buildkernel` and `installkernel` targets build and installthe kernel and the modules (see below).  Please see the top ofthe Makefile in this directory for more information on thestandard build targets and compile-time flags.

Building a kernel is a somewhat more involved process.  See build(7), config(8),

and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
for more information.

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 kernel configuration files reside in the sys/<arch>/confsub-directory.  GENERIC is the default configuration used in release builds.
