# Third-Party Notices

This file is the aggregate ledger of every BSD-derived (not merely
BSD-*inspired*) import in the ManiOS tree, per
[`docs/FOUNDING-PROPOSAL.md` §3.3](../docs/FOUNDING-PROPOSAL.md#33-process-for-any-bsd-derived-import).
Every entry here must correspond to a file (or set of files) under
`third_party/` (or, once imported/adapted, wherever it lands in the
tree) whose original copyright header and license text have been
preserved verbatim.

The licenses also require the notices to go with the binaries: the
build collects every imported file's header into `/boot/etc/notices`
(`tools/mknotices.py`), which is in the boot archive of every ManiOS
build and published with each release as `NOTICES.txt`.

## Entries

The first imports, 0.16 (2026-09-26): programs and C library functions
from OpenBSD, all from OpenBSD's `src` at commit
