No idea why an install of any package, even a command-line one, cannot option out the custom settings in a dialogue with the user, and even run tests, with reports, and thereby confirm a smooth or glitched install with procedures on how to fix, or even option that out as well in the dialogue.
Especially when what I'm trying to install is itself a programming environment!
Any program should walk the uninitiated user through real world projects in a natural order based on the user's spontaneous expressions of a need to know what to do next to complete the project.
