        For those who don't know: TECO is the acronym of Tape Editor and COrrector
        (because it was a paper tape edition tool in its debut days). Now the
        acronym follows after Text Editor and Corrector, or Text Editor
        Character-Oriented.
  
        TECO is a character-oriented text editor, originally developed by Dan
        Murphy at MIT circa 1962. It is also a Turing-complete imperative
        interpreted programming language for text manipulation, done via
        user-loaded sets of macros. In fact, the venerable Emacs was born as a set
        of Editor MACroS for TECO.
  
        TECOC is a portable C implementation of TECO-11.
