#293 rst dograph directive does not exist?

[Chad Dombrova]

the epydoc reStructuredText documentation cites dotgraph as one of the Graphviz directives:

"
.. dotgraph:: [title...]
:caption: text...
graph...

Display a custom Graphviz dot graph...
"

but i get this warning when trying to use it:

"Warning: Line 5: No directive entry for "dotgraph" in module"

is this an omission? coming soon? already available via svn?
it's a very cool feature, would love to have it...
