1 FreeBSD Source: 2 --------------- 3 This is the top level of the FreeBSD source directory. 4 5 FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. 6 A large community has continually developed it for more than thirty years. 7 Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices. 8 9 For copyright information, please see [the file COPYRIGHT](COPYRIGHT) in this directory. 10 Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information. 11 12 The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. 13 See build(7), config(8), [FreeBSD handbook on building userland](https://docs.freebsd.org/en/books/handbook/cutting-edge/#makeworld), and [Handbook for kernels](https://docs.freebsd.org/en/books/handbook/kernelconfig/) for more information, including setting make(1) variables. 14 15 For information on the CPU architectures and platforms supported by FreeBSD, see the [FreeBSD 16 website's Platforms page](https://www.freebsd.org/platforms/). 17 18 Source Roadmap: 19 --------------- 20 | Directory | Description | 21 | --------- | ----------- | 22 | bin | System/user commands. | 23 | cddl | Various commands and libraries under the Common Development and Distribution License. | 24 | contrib | Packages contributed by 3rd parties. | 25 | crypto | Cryptography stuff (see [crypto/README](crypto/README)). | 26 | etc | Template files for /etc. | 27 | gnu | Commands and libraries under the GNU General Public License (GPL) or Lesser General Public License (LGPL).
