Although some companies have budgets that allow them to buy commercial project management software for their architects and project managers, many do not. Because project management software is an essential tool for any large-scale development, there is a value in having an open source (free) alternative. The ProjectTrak project is hosted at <a target="_top" class="url" href="http://projecttrak.sourceforge.net/">http://projecttrak.sourceforge.net/</a>. A <a name="75"></a><a name="IDX-24"></a>subset of the project's use-case analysis is presented in <a class="internaljump" href="#ch02fig01">figure 2.1</a>. A complete set of use cases is distributed with the project's source.</p>
