            The modules are first broken down by which of the device filesystem partitions
            they are installed to. This also includes host tools and testcases which don't
            actually reside in their own partition but convenitely group together.
            <p>
            The makefiles for each partition are further are grouped into a set of directories
            aritrarily picked to break down the problem size by owners.

              <li style="background-color: #fce8e6">Other partner directories are colored red.</li>
            </ul>
            Each of the makefiles are scanned for issues that are likely to come up during
