kandelo — Licensing
=============================

This project uses a split license model, similar to Linux kernel + musl libc:

  - The platform (kernel, host runtime, SDK, build scripts, examples) is
    licensed under the GNU General Public License, version 2 or later
    (GPL-2.0-or-later). See COPYING for the full text.

  - The runtime library components that are linked into user programs
    (libc/musl-overlay/ and libc/glue/) are licensed under the MIT License.
    See COPYING.runtime for the full text.

This means you can compile and run your own programs — including proprietary
ones — on this platform without the GPL applying to your code. The runtime
library code that gets linked into your program (the syscall glue and libc
overlay) is MIT-licensed, and the kernel communicates with your program via
IPC, not linking.

If you modify the platform itself (kernel, host, SDK), those modifications
are covered by the GPL.
