-a ' makes something a quote (ie a string). So:
- '(elem1 elem2 elem3)
-is a list.

-setq makes something a global variable. (?

+The secret to reading [LISP] is to look at
the indenting. You will go mad if you count
the brackets.
-And that
is basically
LISP ;)
+The secret to writing [LISP]
is to always use an editor that autoindents [
LISP] code and highlights matching brackets for you. [Emacs] does this.
-emacs is completely scriptable in LISP
- look in /usr/share/emacs/site
-lisp/*.el for the start
-up and config files.

-Here is an emacs lisp example from po
-mode.el. It only has a maximum of 8 closing brackets in a row, but I didn't look very hard.
