  Darwin
  
     1. <operating system> An operating system based on the
     FreeBSD version of Unix, running on top of a microkernel
     (Mach 3.0 with darwin 1.02) that offers advanced networking,
     services such as the Apache web server, and support for
     both Macintosh and Unix file systems.  Darwin was
     originally released in March 1999.  It currently runs on
     PowerPC based Macintosh computers, and, in October 2000, was
     being ported to Intel processor-based computers and
     compatible systems by the Darwin community.
  
     2. <programming, tool> A general purpose structuring tool of
     use in building complex distributed systems from diverse
     components and diverse component interaction mechanisms.
     Darwin is being developed by the Distributed Software
     Engineering Section of the Department of Computing at
     Imperial College.  It is in essence a declarative binding
     language which can be used to define hierarchic compositions
     of interconnected components.  Distribution is dealt with
     orthogonally to system structuring.  The language allows the
     specification of both static structures and dynamic structures
     which evolve during execution.  The central abstractions
     managed by Darwin are components and services.  Bindings are
     formed by manipulating references to services.
  
     The operational semantics of Darwin is described in terms of
     the Pi-calculus, Milner's calculus of mobile processes.
     The correspondence between the treatment of names in the
     Pi-calculus and the management of service references in Darwin
     leads to an elegant and concise Pi-calculus model of Darwin's
     operational semantics.  The model has proved useful in
     arguing the correctness of Darwin implementations and in
     designing extensions to Darwin and reasoning about their
     behaviour.
