+  The GNU Lesser General Public License or LGPL is written for

+
+  KDE Oxygen theme icons is a special kind of software library, it is an
+  artwork library, it's elements can be used in a Graphical User Interface, or
+  GUI.
+
+  Source code, for this library means:
+   - where they exist, SVG;
+   - otherwise, if applicable, the multi-layered formats xcf or psd, or
+  otherwise png.
+
+  The LGPL in some sections obliges you to make the files carry
+  notices. With images this is in some cases impossible or hardly useful.
+
+  With this library a notice is placed at a prominent place in the directory
+  containing the elements. You may follow this practice.
+
+  The exception in section 5 of the GNU Lesser General Public License covers
+  the use of elements of this art library in a GUI.
