Aside from the exceptions explicitly noted below in the "Other Copyrights" sections, all files in the PLplot package may be distributed under the following terms: This library is free software; you can redistribute it and/or modify it under the terms of the GNU Library General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

You should have received a copy of the GNU Library General Public License along with this library; if not, write to the Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA The text of this license is given in the file COPYING.LIB in the distribution directory. The intent behind distributing the vast majority of PLplot files under the LGPL is to ensure that it continues to evolve in a positive way, while remaining freely distributable. The package is considered a "library" even though there are associated programs, such as plrender, pltek, plserver, and pltcl. The ties between these programs and the library are so great that I consider them as part of the library, so distribution under the terms of the LGPL makes sense. Software developers are allowed and encouraged to use PLplot as an integral part of their product, even a commercial product. Under the conditions of the LGPL, however, the PLplot source code must remain freely available, including any modifications you make to it (if you distribute a program based on the modified library). Please read the full license for more info.

This complete group of CMake-related files sometimes has slightly different licensing language depending on download epoch so look at each of the above files for the definitive source of licensing language. However, in all cases that language is very similar to the modern version of the license for CMake itself which is the OSI-approved BSD 3-clause License (see for further details). ___________________________________________________________________________ Any file that is explicitly marked as "public domain" is free from any restriction on distribution. ___________________________________________________________________________
