   shell
      1. <operating system> (Originally from Multics, widely
      propagated via Unix) The command interpreter used to pass
      commands to an operating system; so called because it is the
      part of the operating system that interfaces with the outside
      world.
      The commonest Unix shells are the c shell (csh) and the
      Bourne shell (sh).
      2. (Or "wrapper") Any interface program that mediates access
      to a special resource or server for convenience, efficiency,
      or security reasons; for this meaning, the usage is usually "a
      shell around" whatever.
