All libraries that are in aRts are licensed under the terms of the GNU Lesser General Public license. The vast majority of the aRts code is in the libraries, including the whole of MCOP and ArtsFlow. This allows the libraries to be used for non-free/non-open source applications if desired.

There are a few programs (such as artsd), that are released under the terms of the GNU General Public License. As there have been different opinions on whether or not linking GPL programs with Qt™ is legal, I also added an explicit notice which allows that, in addition to the GPL: permission is also granted to link this program with the Qt™ library, treating Qt™ like a library that normally accompanies the operating system kernel, whether or not that is in fact the case.
