:"sed" is name of a program on UNIX systems. It stands for Stream
:EDitor, but in a sense, it's now the name of the language understood by
:the program, just a 'C' is the name of the language understood by the C
:compiler.
Top, in case you're thinking, "yeah, but what _is_ it?", if you're
running any flavor of Unix you can type
man sed
at the shell prompt and get something like:
:SED(1) UNIX Reference Manual SED(1)
:
:NAME
: sed - stream editor
:
:SYNOPSIS
: sed [-an] command [file ...]
: sed [-an] [-e command] [-f command_file] [file ...]
:
:DESCRIPTION
: The sed utility reads the specified files, or the standard input if no
: files are specified, modifying the input as specified by a list of com-
: mands. The input is then written to the standard output.
[etc]
A really good book to get is the O'Reilly book _sed & awk_ by Dale
Dougherty.

(No, I don't work for O'Reilly. :)
