Install the cacd tree as follows:

     % cd cacd/src
     % ./domakes install

This builds 50 executables in cacd/bin, six libraries in cacd/lib and puts some
stuff in cacd/lib/sls and cacd/lib/include. If the build of the executable <tool>
fails, I normally do the following thing:

    % cd cacd/src/<tool>
    (... fix the problem ...)
    % source ../sourcethis
    % domake install

The line "source ../sourcethis" causes some crucial environment variables to be set
and it also defines the alias "domake".

Make the cacd tree clean by typing:

    % cd cacd/src
    % ./domakes clean
