3 Organization of Sources:
5 This directory hierarchy is using an organization that separates
6 source for programs that we have obtained from external third
7 parties (where NetBSD is not the primary maintainer) from the
10 The hierarchy is grouped by license, and then package per license,
11 and is organized as follows:
16 Descend into the license sub-directories.
19 Per-license sub-directories.
22 Descend into the package sub-directories.
25 Per-package sub-directories.
31 The third-party source for a given package.
36 BSD makefiles "reach over" from these into
39 This arrangement allows for packages to be easily disabled or
40 excised as necessary, either on a per-license or per-package basis.
42 The licenses currently used are:
44 apache2 Apache 2.0 license.
45 http://www.opensource.org/licenses/apache2.0.php
47 atheros Atheros License.
49 bsd BSD (or equivalent) licensed software, possibly with
50 the "advertising clause".

73 intel-fw-public Intel firmware license permitting redistribution with
74 terms similar to BSD licensed software.

83 into the Public Domain.

90 If a package has components covered by different licenses
91 (for example, GPL2 and the LGPL), use the <license> subdirectory
92 for the more restrictive license.
94 If a package allows the choice of a license to use, we'll
95 generally use the less restrictive license.
97 If in doubt about where a package should be located, please
98 contact <core@NetBSD.org> for advice.
104 Eventually src/dist (and associated framework in other base source
105 directories) and src/gnu will be migrated to this hierarchy.
108 Maintenance Strategy:
110 The sources under src/external/<license>/<package>/dist/ are
111 generally a combination of a published distribution plus changes
112 that we submit to the maintainers and that are not yet published
115 Make sure all changes made to the external sources are submitted
116 to the appropriate maintainer, but only after coordinating with
117 the NetBSD maintainers.
