1$NetBSD: README,v 1.15 2012/06/14 04:14:36 riz 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 public-domain Non-license for code that has been explicitly put 83 into the Public Domain. 84 85 realtek RealTek license. 86 87 zlib Zlib (BSD-like) license. 88 http://www.zlib.net/zlib_license.html 89 90If a package has components covered by different licenses 91(for example, GPL2 and the LGPL), use the <license> subdirectory 92for the more restrictive license. 93 94If a package allows the choice of a license to use, we'll 95generally use the less restrictive license. 96 97If in doubt about where a package should be located, please 98contact <core@NetBSD.org> for advice. 99 100 101Migration Strategy: 102 103 104Eventually src/dist (and associated framework in other base source 105directories) and src/gnu will be migrated to this hierarchy. 106 107 108Maintenance Strategy: 109 110The sources under src/external/<license>/<package>/dist/ are 111generally a combination of a published distribution plus changes 112that we submit to the maintainers and that are not yet published 113by them. 114 115Make sure all changes made to the external sources are submitted 116to the appropriate maintainer, but only after coordinating with 117the NetBSD maintainers. 118
