The original Berkeley Software Distributions were made in the 1980's and 1990's. At that time, the Buenos Ares Convention of 1910 was in force in most of the countries in the Americas. It required an affirmative statement of rights reservation, typically using 'All Rights Reserved.' The Regents included this phrase in their copyright notices to invoke this treaty to ensure maximal copyright protection. In the 1990's, Latin America coutries ratifeid the Berne Convention on copyrights which prohibited them from requiring an affirmative statement to reserve the rights. When Nicaragua ratified in 2000, the Buenos Ares Convention of 1910 was effectively repealed. This made all the 'All Rights Reserved' phrases obsolete and legal deadweight most of the time, and certainly in the cases removed here. Since it's no longer required, and is in fact meaningless, core has decided to dropped it from the project's collection copyright and sample templates. It encourages other rights holders to do the same after consultation with their legal department. More see https://en.wikipedia.org/wiki/Buenos_Aires_Convention for more information.

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. See build(7) and https://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 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. See build(7), config(8), and https://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>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
devices, not just those commonly used.
