The UFRaw (Unidentified Flying Raw) is a tool for reading and manipulating
raw images from digital cameras.  It supports most of the existing raw
formats (any format supported by DCRaw).  UFRaw can be used on its own or
as a Gimp plug-in.

UFRaw depends on dcraw, which is also available at SlackBuilds.org.
However, you can add "--enable-extras" to the configure arguments in the
build script to use the included dcraw.

UFRaw requires gtkimageview to include the image preview window. You can
build it without gtkimageview (run with GTK=no) but you'll only have
command line interface to UFRaw.

Lensfun library is now autodetected.
