          1.  {A. K. Erlang}.  (The other senses were named
          after him).
       
          2.  A concurrent {functional language} for large
          industrial {real-time} systems by Armstrong, Williams and
          Virding of Ellemtel, Sweden.
       
          Erlang is untyped.  It has {pattern matching} syntax,
          {recursion equations}, explicit {concurrency}, {asynchronous
          message passing} and is relatively free from {side-effects}.
          It supports transparent cross-{platform} distribution.  It has
          primitives for detecting run-time errors, real-time {garbage
          collection}, {modules}, {dynamic code replacement} (change
          code in a continuously running real-time system) and a
          {foreign language interface}.
       
          An unsupported free version is available (subject to a
          non-commercial licence).  Commercial versions with support are
          available from {Erlang Systems AB}.  An {interpreter} in
          {SICStus Prolog} and compilers in {C} and Erlang are available
          for several {Unix} {platforms}.
       
          {Open Telecom Platform} (OTP) is a set of {libraries} and
          tools.

          3.  36 {CCS} per hour, or 1 call-second per second.
       
          Erlang is a unit without dimension, accepted internationally
          for measuring the traffic intensity.  This unit is defined as
          the aggregate of continuous occupation of a channel for one
          hour (3600 seconds).  An intensity of one Erlang means the
          channel is continuously occupied.
