CASL owes some of its code to freely available packages.  We would like
to recognize and thank the various authors who provided their code freely
to the public and in so doing contributed to the development of CASL.

- CASL uses GNU's CPP (the C pre-processor) to preprocess CASL scripts.
  GNU CPP is copyright by the Free Software Foundation.  In accordance
  with the GPL, we are making the source code available as part of this
  distribution.  The file cpp-src.tar.gz contains the source code we used
  to build CPP for CASL.  Also included in the tar file is the GPL license 
  which covers this software in a file called COPYING.

- CASL uses libpcap, the packet capture library, from Lawrence Berkeley
  Labs (ftp.ee.lbl.gov).  In accordance with the libpcap license we note:

  This product includes software developed by the University of California,
  Lawrence Berkeley Laboratory and its contributors.

- CASL uses the strsep function from the FreeBSD project, which in turn
  is derived from the Berkeley Software Distribution.  In accordance with
  the license covering this software we note:

       This product includes software developed by the University of
       California, Berkeley and its contributors.
