## Summary:

  # TECO.EL

  TECO was an ancient text editor written in the days before most of you
  reading this were born.  It supported macros of editing commands as an
  extension mechanism.  The original version of EMACS was written by
  loading macros into TECO that provided EMACS functionality and then
  saving the memory image of the combined TECO command interpreter and
  the macros as a new program ("dumping an EMACS").
