   (description
    "Sed is a non-interactive, text stream editor.  It receives a text
input from a file or from standard input and it then applies a series of text
editing commands to the stream and prints its output to standard output.  It
is often used for substituting text patterns in a stream.  The GNU
implementation offers several extensions over the standard utility.")
