The GNU ed line editor
**********************

This manual is for GNU ed (version 0.7, 18 July 2007).


   GNU ed is an 8-bit clean, more or less POSIX-compliant
implementation of the standard Unix line editor. These days,
full-screen editors have rendered `ed' mostly of historical interest.
Nonetheless, it appeals to a handful of aging programmers who still
believe that "Small is Beautiful".
