Additionally, this software package incorporates various pieces of code licensed under the BSD or MIT licenses and their variants. This adds the additional requirement of mentioning the respective authors and licenses in binary distributions as well. Obviously, these licenses must also be kept in the source.

Some of these may be used in the form of dynamically linked libraries distributed separately, most notably libudt. In that case, the respective licenses do not apply to the binary of this software. Also, some of the files are only used for building binaries of this software, without becoming an actual part of those binaries.
