- general flow of the main loop
I'm sorry, but there is no 10-20 lines about it. When you say "main loop", I assume you mean installing a mod?
- elkhound part (what's for, can be replaced?)
A short description can be found in the project's
readme. For a slightly longer description, there's a link to McPeak's old web page. It's still informative, though some of the comparisons are outdated.
- backup system new logic
What are you referring to?
- components/groups etc
I'm going to have to refer to the readme. If there is something you are missing, you'll need to be more specific.
- other related things
If it's not in the readme, I'm going to have to ask you to be more specific.
