+      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.
