1$NetBSD: README,v 1.9 2010/05/01 19:51:33 christos 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 bsd BSD (or equivalent) licensed software, possibly with 48 the "advertising clause". 49 http://www.opensource.org/licenses/bsd-license.php 50 51 cddl Common Development and Distribution License (the sun 52 license which is based on the Mozilla Public License 53 version 1.1). 54 http://www.opensource.org/licenses/cddl1.php 55 56 gpl2 GNU Public License, version 2 (or earlier). 57 http://www.opensource.org/licenses/gpl-2.0.php 58 59 gpl3 GNU Public License, version 3. 60 http://www.opensource.org/licenses/gpl-3.0.html 61 62 ibm-public IBM's public license: 63 http://www.opensource.org/licenses/ibmpl.php 64 65 intel-fw-eula Intel firmware license with redistribution 66 restricted to OEM. 67 68 intel-fw-public Intel firmware license permitting redistribution with 69 terms similar to BSD licensed software. 70 71 intel-public Intel license permitting redistribution with 72 terms similar to BSD licensed software. 73 74 mit MIT (X11) style license. 75 http://www.opensource.org/licenses/mit-license.php 76 77If a package has components covered by different licenses 78(for example, GPL2 and the LGPL), use the <license> subdirectory 79for the more restrictive license. 80 81If a package allows the choice of a license to use, we'll 82generally use the less restrictive license. 83 84If in doubt about where a package should be located, please 85contact <core@NetBSD.org> for advice. 86 87 88Migration Strategy: 89 90 91Eventually src/dist (and associated framework in other base source 92directories) and src/gnu will be migrated to this hierarchy. 93 94 95Maintenance Strategy: 96 97The sources under src/external/<license>/<package>/dist/ are 98generally a combination of a published distribution plus changes 99that we submit to the maintainers and that are not yet published 100by them. 101 102Make sure all changes made to the external sources are submitted 103to the appropriate maintainer, but only after coordinating with 104the NetBSD maintainers. 105
