All the icons in this directory (and its subdirectories) were made for ElmerGUI by
using icons in Tango icon theme which is in the public domain. Some icons were just
taken from Tango icon theme and others were generated by combining some icons in 
Tango icon theme. Tango icon theme was developed in Tango Desktop Project.
