+# Dependency description / Maintainer-Info:
+
+# Rendering is done via the following plugins (/plugins):
+# - core, dot_layout, neato_layout, gd , dot
+# the ones which are always compiled in, depend on zlib, gd
+# - gtk
+# Directly depends on gtk-2.
+# needs 'pangocairo' enabled in graphviz configuration
+# gtk-2 depends on pango, cairo and libX11 directly.
+# - gdk-pixbuf
+# Disabled, GTK-1 junk.
+# - glitz
+# Disabled, no particular reason
+# needs 'pangocairo' enabled in graphviz configuration
+# - ming
+# flash plugin via -Tswf requires media-libs/ming-0.4. Disabled as it's
+# incomplete.
+# - cairo/pango:
+# Needs pango for text layout, uses cairo methods to draw stuff
+# - xlib:
+# needs cairo+pango,
+# can make use of gnomeui and inotify support (??? unsure),
+# needs libXaw for UI
+# UI also links directly against libX11, libXmu, and libXt
+# and uses libXpm if available so we make sure it always is
+
+# There can be swig-generated bindings for the following languages (/tclpkg/gv):
+# - c-sharp (disabled)
+# - scheme (enabled via guile) ... no longer broken on ~x86
+# - io (disabled)
+# - java (enabled via java) *2
+# - lua (enabled via lua)
+# - ocaml (enabled via ocaml)
+# - perl (enabled via perl) *1
+# - php (enabled via php) *2
+# - python (enabled via python) *1
+# - ruby (enabled via ruby) *1
+# - tcl (enabled via tcl)
+# *1 = The ${P}-bindings.patch takes care that those bindings are installed to the right location
+# *2 = Those bindings don't build because the paths for the headers/libs aren't
+# detected correctly and/or the options passed to swig are wrong (-php instead of -php4/5)
+
+# There are several other tools in /tclpkg:
+# gdtclft, tcldot, tclhandle, tclpathplan, tclstubs ; enabled with: --with-tcl
+# tkspline, tkstubs ; enabled with: --with-tk
+
+# And the commands (/cmd):
+# - dot, dotty, gvedit, gvpr, lefty, lneato, smyrna, tools/* :)
+# sci-libs/gts can be used for some of these
+# - lefty:
+# needs Xaw and X to build
+# - gvedit (via 'qt5'):
+# based on ./configure it needs qt-core and qt-gui only
+# - smyrna : experimental opengl front-end (via 'smyrna')
+# currently disabled -- it segfaults a lot
+# needs x11-libs/gtkglext, gnome-base/libglade, media-libs/freeglut
+# sci-libs/gts, x11-libs/gtk. Also needs 'gtk','glade','glut','gts' and 'png'
+# with flags enabled at configure time
