# NOTE: Even current libav 11.4 does not have AV_CODEC_CAP_VARIABLE_FRAME_SIZE
#       so there is no chance to support libav right now (Gentoo bug #567638)
#       If it returns, please check prior GEGL ebuilds for how libav was integrated.  Thanks!

	# disable documentation as the generating is bit automagic
	#    if anyone wants to work on it just create bug with patch

	# Also please note that:
	#
	#  - Some auto-detections are not patched away since the docs are
	#    not built (--disable-docs, lack of --enable-gtk-doc) and these
	#    tools affect re-generation of docs, only
	#    (e.g. ruby, asciidoc, dot (of graphviz), enscript)
	#
	#  - Parameter --with-exiv2 compiles a noinst-app only, no use
	#
	#  - Parameter --disable-workshop disables any use of Lua, effectivly
	#
	#  - v4l support does not work with our media-libs/libv4l-0.8.9,
	#    upstream bug at https://bugzilla.gnome.org/show_bug.cgi?id=654675
	#
	#  - There are two checks for dot, one controllable by --with(out)-graphviz
	#    which toggles HAVE_GRAPHVIZ that is not used anywhere.  Yes.
	#
	#  - mrg is not in tree and gexiv2 support only has effect when mrg support
	#    is enabled
	#
	# So that's why USE="exif graphviz lua v4l" got resolved.  More at:
