1$NetBSD: README,v 1.18 2020/11/10 11:00:02 gson Exp $ 2 3Organization of Sources: 4 5This directory hierarchy is using an organization that separates 6source for programs that we have obtained from external third 7parties (where NetBSD is not the primary maintainer) from the 8system source. 9 10The hierarchy is grouped by license, and then package per license, 11and is organized as follows: 12 13 external/ 14 15 Makefile 16 Descend into the license sub-directories. 17 18 <license>/ 19 Per-license sub-directories. 20 21 Makefile 22 Descend into the package sub-directories. 23 24 <package>/ 25 Per-package sub-directories. 26 27 Makefile 28 Build the package. 29 30 dist/ 31 The third-party source for a given package. 32 33 bin/ 34 lib/ 35 sbin/ 36 BSD makefiles "reach over" from these into 37 "../dist/". 38 39This arrangement allows for packages to be easily disabled or 40excised as necessary, either on a per-license or per-package basis. 41 42The licenses currently used are: 43 44 apache2 Apache 2.0 license. 45 http://www.opensource.org/licenses/apache2.0.php 46 47 atheros Atheros License. 48 49 bsd BSD (or equivalent) licensed software, possibly with 50 the "advertising clause". 51 http://www.opensource.org/licenses/bsd-license.php 52 53 cddl Common Development and Distribution License (the sun 54 license which is based on the Mozilla Public License 55 version 1.1). 56 http://www.opensource.org/licenses/cddl1.php 57 58 gpl2 GNU Public License, version 2 (or earlier). 59 http://www.opensource.org/licenses/gpl-2.0.php 60 61 gpl3 GNU Public License, version 3. 62 http://www.opensource.org/licenses/gpl-3.0.html 63 64 historical Lucent's old license: 65 http://www.opensource.org/licenses/historical.php 66 67 ibm-public IBM's public license: 68 http://www.opensource.org/licenses/ibmpl.php 69 70 intel-fw-eula Intel firmware license with redistribution 71 restricted to OEM. 72 73 intel-fw-public Intel firmware license permitting redistribution with 74 terms similar to BSD licensed software. 75 76 intel-public Intel license permitting redistribution with 77 terms similar to BSD licensed software. 78 79 mit MIT (X11) style license. 80 http://www.opensource.org/licenses/mit-license.php 81 82 mpl Mozilla Public license. 83 https://opensource.org/licenses/MPL-2.0 84 85 nvidia-firmware NVIDIA firmware license permitting redistribution for 86 use on operating systems distributed under the terms 87 of an OSI-approved open source license. 88 89 public-domain Non-license for code that has been explicitly put 90 into the Public Domain. 91 92 realtek RealTek license. 93 94 zlib Zlib (BSD-like) license. 95 http://www.zlib.net/zlib_license.html 96 97If a package has components covered by different licenses 98(for example, GPL2 and the LGPL), use the <license> subdirectory 99for the more restrictive license. 100 101If a package allows the choice of a license to use, we'll 102generally use the less restrictive license. 103 104If in doubt about where a package should be located, please 105contact <core@NetBSD.org> for advice. 106 107 108Migration Strategy: 109 110 111Eventually src/dist (and associated framework in other base source 112directories) and src/gnu will be migrated to this hierarchy. 113 114 115Maintenance Strategy: 116 117The sources under src/external/<license>/<package>/dist/ are 118generally a combination of a published distribution plus changes 119that we submit to the maintainers and that are not yet published 120by them. 121 122Make sure all changes made to the external sources are submitted 123to the appropriate maintainer, but only after coordinating with 124the NetBSD maintainers. 125
