# Icon Licenses #
######################################################

Open Icon Library currently uses icons from many different
sources, using various free/open licenses. This file lists the
various sources and their respective licenses. For more
detailed documentation of the icons licenses, authors and
file lists see the docs/ folder.

Icons from the various sources are stored in the developers
package, open_icon_library-devel. Each source is place in a
separate directories, whose name is listed below. The
open_icon_library-full, open_icon_library-CC,
open_icon_library-GPL, and open_icon_library-PD packages have
the various sources combined, and sorted file type and image
size. To see which icons came from which packages look it
the 'docs' directory for the FILELIST files, or download the
developers package. To see how they are combined download the
developers package or icon_tools package, and look at
the icon-tools/make_directories_stageX.sh scripts.

In addition these documents, each file is embeded with its
license and source in the metadata.
