Hi Quiliro,

can you access this? I don't know how much JavaScript a browser, or
wget, needs to access this PDF...

  https://arxiv.org/pdf/1612.09375.pdf#page=80

The important paragraph is this one:

  In his excellent book Mathematics: A Very Short Introduction,
  Timothy Gowers (2002) considers the question: `What is the black
  king in chess?' He swiftly points out that this question is rather
  peculiar. It is not important that the black king is a small piece
  of wood, painted a certain colour and carved into a certain shape.
  We could equally well use a scrap of paper with `BK' written on it.
  What matters is what the black king _does_: it can move in certain
  ways but not others, according to the rules of chess.

There are many questions about eev that I find very hard to answer
because they are like the question "What is the black king in chess?"
above. It is very easy to show what a certain sexp or e-script... - obs:
this tutorial

  (find-here-links-intro)

starts with this paragraph:

  Eev's central idea is that you can keep "executable logs" of what
  you do, in a format that is reasonably readable and that is easy to
  "play back" later, step by step and in any order. We call these
  executable logs, or executable notes, "e-scripts".

which answer your question about what are e-scripts...

...again: it is very easy to show what a certain sexp or what a
certain e-script _do_ when they are executed, but it is much harder to
explain what they _are_...
