* INTRODUCTION *
****************
The vast majority of this implementation is subject to the standard
3-clause BSD license. Copyright is held by Three Rings Design and
Landon Fuller, and the license and official copyright can be found at
the bottom of this file.
Small portions of the implementation were taken from various sources, including:
- FreeBSD libc (strlcpy)
- FreeBSD kernel (pf ioctl validation)
- kazlib (hash table implementation)
- PLInstrument (test runner framework)
- SenTestCase (test assertion macros)
Associated copyrights and licenses are documented below. All code included
in the final product are either made available under the BSD license, or
under an compatible and equivalently permissive license.
Some additional sources are included with this distribution and used as a part
of the build process; they are not linked with the final product:
- The lemon parser generator - Public Domain (http://www.hwaci.com/sw/lemon/)
- Makeheaders - GPL (http://www.hwaci.com/sw/mkhdr/)
