Any chance of more info on what RDkit contains? E.g. an API, or a website. Although Open Source projects are infamous for incomplete documentation, you seem to have taken this to an extreme :-)
I'm involved in other open source cheminformatics packages (via the BlueObelisk, with varying degrees of documentation it must be admitted) so it would be good to know to what extent there is overlap, and whether we could share code, etc... Noel
