      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.
