  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  shell  [orig.  {{Multics}}  n.  techspeak  widely  propagated  via 
  Unix]  1.  [techspeak]  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.  2.  More  generally,  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.  This  sort  of  program 
  is  also  called  a  `wrapper'.  3.  A  skeleton  program,  created  by  hand  or 
  by  another  program  (like,  say  a  parser  generator),  which  provides  the 
  necessary  {incantation}s  to  set  up  some  task  and  the  control  flow  to  drive 
  it  (the  term  {driver}  is  sometimes  used  synonymously).  The  user  is  meant 
  to  fill  in  whatever  code  is  needed  to  get  real  work  done  This  usage  is 
  common  in  the  AI  and  Microsoft  Windows  worlds,  and  confuses  Unix  hackers. 
 
  Historical  note:  Apparently,  the  original  Multics  shell  (sense  1) 
  was  so  called  because  it  was  a  shell  (sense  3);  it  ran  user  programs 
  not  by  starting  up  separate  processes,  but  by  dynamically  linking 
  the  programs  into  its  own  code,  calling  them  as  subroutines,  and  then 
  dynamically  de-linking  them  on  return.  The  VMS  command  interpreter 
  still  does  something  very  like  this
