五OS Developer License

The 五OS Developer License is meant to be used for all elements of 五SDK, the 五OS SDK.

Why

The kernel includes contains structures and logic, and took a relatively high amount of time to be written. All 五OS include files are released under this license unless something else is specified in the file's header.

Rules

The license is BSD-like license, without any effect on binary delivered for the 五OS platform.

This means that if you release a software which use a 五OS include for 五OS, there's nothing you need to do. If you release the same software, or any other software using 五OS includes for another platform, you will have to comply with terms identical to the BSD license (usually it won't be the case, as these includes are only for 五OS).

In case of source distribution, you can include/modify 五OS includes in your distribution (this is not a good idea), as long as you keep the copyright intact.
