Getting ATLAS to use your shiny new defaults

If necessary, rename the tarfile with your archdefs to the same name as the architecture you are presently compiling on (normally the file will already have the same name). Then, during configure, you simply tell ATLAS to use your directory of architectural defaults, by adding the following flag to configure:

   -Ss ADdir <path to directory containing your tarfile>

Note that with this flag and ability to make archdefs, you can create an enire suite of custom archdefs for your particular machines, and keep them all together in a directory for future installs.
