| <blockquote> |

| |
| <p>The text of the above license is included in the file LICENSE in the source.</p> |
| |
| <h2>Why 0BSD?</h2> |
| |
| <p>As with <a href=https://creativecommons.org/publicdomain/zero/1.0/>CC0</a>, |
| <a href=http://unlicense.org>unlicense</a>, and <a href=http://wtfpl.net/>wtfpl</a>, |
| the intent is to place the licensed material into the public domain, |
| which after decades of FUD (such as the time OSI's ex-lawyer compared |
| <a href=http://www.cod5.org/archive/>placing code into the public domain</a> to |
| <a href=http://www.linuxjournal.com/article/6225>abandoning trash by the |
| side of a highway</a>) is considered somehow unsafe. But if some random third |
| party |
| <a href=https://github.com/mkj/dropbear/blob/master/libtomcrypt/LICENSE>takes |
| public domain code</a> and slaps <a href=http://www.opensource.apple.com/source/gnuzip/gnuzip-25/gzip/gzip.c>some other license on it</a>, then it's fine.</p> |
| |
| <p>To work around this perception, the above license is a standard 2-clause BSD |
| license <a href=https://github.com/landley/toybox/commit/ee86b1d8e25cb0ca9d418b33eb0dc5e7716ddc1e>minus the half sentence</a> |
| requiring text copied verbatim into derived works. If 2BSD is |
| ok, the 0BSD should be ok, despite being equivalent to placing code in the |
| public domain.</p> |
| |
| <p>Modifying the license in this way avoids the hole android toolbox fell into where |
| <a href=https://github.com/android/platform_system_core/blob/fd4c6b0a3a25921a9fe24691a695d715aecb6afe/toolbox/NOTICE>33 copies of BSD license text</a> |
| were concatenated together when copyright dates changed, or the strange |
| solution the busybox developers used to resolve tension between GPLv2's "no |
| additional restrictions" and BSD's "you must include this large hunk of text" |
| by sticking the two licenses at |
| <a href=http://git.busybox.net/busybox/tree/networking/ping.c?id=887a1ad57fe978cd320be358effbe66df8a068bf>opposite ends of the file</a> and hoping nobody |
| noticed.</a> |
