- get a GraphViz binary release, can be pared down to the following files:

[.]                         [..]                        cairo.dll
cdt.dll                     cgraph.dll                  config6
COPYING_GraphViz.txt        dot.exe                     expat.dll
fontconfig.dll              glib-2.dll                  gobject-2.dll
gvc.dll                     gvplugin_core.dll           gvplugin_dot_layout.dll
gvplugin_neato_layout.dll   gvplugin_pango.dll          libharfbuzz-0.dll
pango-1.dll                 pangocairo-1.dll            pangoft2-1.dll
pangowin32-1.dll            Pathplan.dll                pixman-1.dll
twopi.exe                   xdot.dll

- config6 provides a minimalist config to use w/ the binaries

- cp dot.exe twopi.exe (these use arv0 to determine behaviour, qcg/kcg needs both)
