    <title>Start and stop windows and servers</title>

    <p>The main process in Reltool is the server. It can be used as it
    is or be used via the GUI frontend process. When the GUI is
    started, a server process will automatically be started. The GUI
    process is started with <c>reltool:start/0</c>,
    <c>reltool:start/1</c> or <c>reltool:start_link/1</c>. The pid of
    its server can be obtained with <c>reltool:get_server/1</c></p>
