Apologies for my delay in reply!
RE: I would like to understand how to make a website directory entirely out of the Connections Plugin, so even the site pages are generated dynamically from Connections rather than from WordPress, – I know this is possible, and I would prefer to do it myself rather than uses a consultant.
I suppose this could be possible but Connections is really designed to be embedded on a page. So, you would need at least one. Probably the one that you would set as your static homepage in the WP settings. You could use the shortcode or the new WP5 editor block.
On the Connections Settings admin page under the Advanced tab you could enable all the permalink options. In combination with the Enhanced Categories extension and the cMap template (with its category dropdown filter displabled)
With that, I guess the entire site would be Connections powered. It really depends on what the envisioned goal is.
Doing this what just using the Connections codebase is probably feasible too. I guess it really depends on the desired end goal.
In regards to documentation, depending on when you last looked, there is a lot more of it. But, it is primarily focused around using Connections and its addons, not the code. The code itself is documented inline using phpDoc. I guess that is what you mean by the Linux man pages.
RE: I would like to have one single upgrade price for the full suite, for multiple sites. – you can see my purchase history and let me know which will be best for me.
I see you’ve purchased the Pro Pack, you can renew it for a discounted price if $59.99.
Not sure how helpful this is, but I do hope it is!
