It does help, to some extent.  But I'm still in the dark regarding
some aspects of this.  I'll keep asking questions, but there's a limit
to which I feel myself entitled to ask questions without annoying too
much.  Which is why I suggested to write commentary instead, to get
some of the basics out of the way.  It doesn't have to be you
personally who writes the commentary, btw: anyone who knows the
answers to the questions I posted could do that.  With that in mind,
let me again post the questions which I'm currently struggling with:

  . what are "roots"?
  . what is the purpose of each root_create_SOMETHING function in igc.c?
  . what is the difference between "exact" and "ambiguous" roots, and
    when should we use each one in Emacs?
