ivl license explained

ivl can be used in both free open-source projects and in commercial proprietary closed-source projects. For this reason it is released under two alternative licenses.

The LGPL 3.0 license allows the use in open-source and/or commercial closed-source projects provided that its terms are satisfied. Template C++ header-only code--which is prominent in ivl--is handled in Section 3 of the license. ivl template code meets the mentioned requirements and thus the terms to be satisfied [for using the actual templates only] are:


		Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License.
		Accompany the object code with a copy of the GNU GPL and this license document.

The non-header source code of ivl like the code of modules ivl-lina and ivl-cv needs to satisfy more terms as explained in the license.

The GPL 2.0 license allows compatibility with open-source projects licensed under GPL 2.0.

Users of the ivl library may chose freely the one of the two alternative licenses that is more appropriate to their specific use.
