+3. newlib
+   The C library "newlib" is used to build user-level aplications on the top
+   of eduOS. Newlib is a collection of source code, it is
+   distributed under the terms of several different licenses. All of the
+   licensing is either public domain or BSD-like, which means that even
+   proprietary applications can adopt newlib because its use does not
+   require distribution of the end work's source code. For convenience, all
+   of newlib's licenses are gathered up into the file COPYING.NEWLIB,
+   which is included in the directory newlib or in newlib's source code.
