-      Sed (stream editor) isn't really a true text editor or text
-      processor.  Instead, it is used to filter text, i.e., it takes
-      text input and performs some operation (or set of operations) on
-      it and outputs the modified text.  Sed is typically used for
-      extracting part of a file using pattern matching or substituting
-      multiple occurrences of a string within a file.
