This simple program generates thumbnails of digital camera raw image files
using libopenraw and GDK. It supports the same file formats as libopenraw
<http://libopenraw.freedesktop.org/wiki/FileFormats>.
This thumbnailer is designed to be small, lightweight, and fast. It is
primarily intended to be used with file managers (although it could easily
be used by a photograph management program) and is used by thunar-thumbnailers.
Usage: raw-thumbnailer -i input_file -o output_file -s size
raw-thumbnailer requires libopenraw (also available at SlackBuilds.org).
