# E-scripts on APL.
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
#   (find-eev-quick-intro)
#   http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

#   The k binary weighs in at about 50Kb. Someone asked about the
#   interpreter source code. A frown flickered across the face of our
#   visitor from Microsoft: what could be interesting about that? "The
#   source is currently 264 lines of C," said Arthur. I thought I
#   heard a sotto voce "that's not possible." Arthur showed us how he
#   had arranged his source code in five files so that he could edit
#   any one of them without scrolling. "Hate scrolling," he mumbled.
