Organization of Sources:
|
|
|
|
This directory hierarchy is using an organization that separates
|
|
source for programs that we have obtained from external third
|
|
parties (where NetBSD is not the primary maintainer) from the
|
|
system source.
|
|
|
|
The hierarchy is grouped by license, and then package per license,
|
|
and is organized as follows:
|
|
|
|
external/
|
|
|
|
Makefile
|
|
Descend into the license sub-directories.
|
|
|
|
<license>/
|
|
Per-license sub-directories.
|
|
|
|
Makefile
|
|
Descend into the package sub-directories.
|
|
|
|
<package>/
|
|
Per-package sub-directories.
|
|
|
|
Makefile
|
|
Build the package.
|
|
|
|
dist/
|
|
The third-party source for a given package.
|
|
|
|
bin/
|
|
lib/
|
|
sbin/
|
|
BSD makefiles "reach over" from these into
|
|
"../dist/".
|
|
|
|
This arrangement allows for packages to be easily disabled or
|
|
excised as necessary, either on a per-license or per-package basis.
|
|
|
|
The licenses currently used are:
|
|
|

|
|
|
|
If a package has components covered by different licenses
|
|
(for example, GPL2 and the LGPL), use the <license> subdirectory
|
|
for the more restrictive license.
|
|
|
|
If a package allows the choice of a license to use, we'll
|
|
generally use the less restrictive license.
|
|
|
|
If in doubt about where a package should be located, please
|
|
contact <core@NetBSD.org> for advice.

|
Migration Strategy:
|
|
|
|
|
|
Eventually src/dist (and associated framework in other base source
|
|
directories) and src/gnu will be migrated to this hierarchy.
|
|
|
|
|
|
Maintenance Strategy:
|
|
|
|
The sources under src/external/<license>/<package>/dist/ are
|
|
generally a combination of a published distribution plus changes
|
|
that we submit to the maintainers and that are not yet published
|
|
by them.
|
|
|
|
Make sure all changes made to the external sources are submitted
|
|
to the appropriate maintainer, but only after coordinating with
|
|
the NetBSD maintainers.
