wget, needs to access this PDF...
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:
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_...
