 Introduction
 ************
 
    `sed' is a stream editor.  A stream editor is used to perform basic
 text transformations on an input stream (a file or input from a
 pipeline).  While in some ways similar to an editor which permits
 scripted edits (such as `ed'), `sed' works by making only one pass over
 the input(s), and is consequently more efficient.  But it is `sed''s
 ability to filter text in a pipeline which particularly distinguishes
 it from other types of editors.
