Incorporated code

A number of pieces of external code are included in the Exim distribution.

• Regular expressions are supported in the main Exim program and in the Exim monitor using the freely-distributable PCRE library, copyright (c) 1998 University of Cambridge. The source is distributed in the directory `src/pcre'.
• RFC 1413 callbacks are supported in the main Exim program using the `libident' library made freely available by Peter Eriksson at `ftp.lysator.liu.se'. Some modifications have been made in order to support IPv6. The source is distributed in the directory called `src/libident'.
• Support for the cdb (Constant DataBase) lookup method is provided by code contributed by Nigel Metheringham of Planet Online Ltd. which contains the following statements: --------------------------------------------------------------------
