need intersphinx_mapping for graph_tool

graph-tool
1

I'm writing some documentation using Sphinx and I would like to reference
graph_tool.

Is this the correct intersphinx_mapping?

    'graph_tool': ('https://graph-tool.skewed.de/static/doc/',None),

If so, I am still having trouble referencing graph_tool using markdown such
as:

    :py:mod:`graph_tool`

or even

    :mod:`graph_tool`

and it is not picking up the link. What am I missing here?

Thanks!
