TrustedBSD extensions are intended for use with the FreeBSD operating system, a liberally licensed free operating system based on the Berkeley UNIX variant, BSD. The extensions are released under a two-clause BSD license, copyright held by the authors of the component in question. This license permits both commercial and non-commercial use of the code, providing that the copyright is observed and documented, and that the authors may not be held liable for damages associated with use of the code. Generally speaking, this places few if any restrictions on any real-world use, and legally consumers of the code are under no obligation to provide compensation to the authors. However, machinery is in place to accept donations to the TrustedBSD project to allow further development, if anyone is interested. If you are interested in this opportunity, please email trustedbsd-finances@@TrustedBSD.org for more information.
