+Component "Synthesis ToolKit" license:
+
+The Synthesis ToolKit in C++ (STK) is a set of open source audio
+signal processing and algorithmic synthesis classes written in the
+C++ programming language. STK was designed to facilitate rapid
+development of music synthesis and audio processing software, with
+an emphasis on cross-platform functionality, realtime control,
+ease of use, and educational example code.  STK currently runs
+with realtime support (audio and MIDI) on Linux, Macintosh OS X,
+and Windows computer platforms. Generic, non-realtime support has
+been tested under NeXTStep, Sun, and other platforms and should
+work with any standard C++ compiler.
