ed: n. "ed is the standard text editor." Line taken from
original the Unix manual page on ed, an ancient line-oriented
editor that is by now used only by a few Real Programmers, and
even then only for batch operations. The original line is sometimes
uttered near the beginning of an emacs vs. vi holy war on Usenet,
with the (vain) hope to quench the discussion before it really takes
off. Often followed by a standard text describing the many virtues
of ed (such as the small memory footprint on a Timex Sinclair, and
the consistent (because nearly non-existent) user interface).
