I’m a little bit surprised by this. I just tried on my machine (obus.1.2.2, odoc.1.4.2 and odig.0.0.4) and there’s no less documentation that can be found in the doc strings.
These incantations should not be needed. AFAIK this will generate the HTML documentation “on the side” but it shouldn’t be that different from what odig generate: obus installs its cmti files so odig can do its job.
Could you please indicate what the problem is in more details ?
