# Dependency description / Maintainer-Info:

# Rendering is done via the following plugins (/plugins):
# - core, dot_layout, neato_layout, gd (the ones which are always compiled in, depend on zlib, gd)
# - gtk (depends on gtk-2, cairo, libX11, gtk-2 depends on cairo and libX11 as well)
# - ming ( depends on ming-3.0 which is still p.masked)
# - pango ( depends on pango and cairo, but pango depends on cairo as well)
# - xlib ( depends on libX11, Xrender AND pango, can make use of gnomeui and inotify support)
# - ming ( depends on ming-3 which is still masked, ?)

# There can be swig-generated bindings for the following languages (/tclpkg/gv):
# - c-sharp (disabled)
# - scheme (enabled via guile) ... 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, gvpr, lefty, lneato, tools/* :)
# Lefty needs Xaw and X to build
