    <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
    <seemfa marker="reltool#start/0"><c>reltool:start/0</c></seemfa>,
    <seemfa marker="reltool#start/1"><c>reltool:start/1</c></seemfa> or
    <seemfa marker="reltool#start_link/1"><c>reltool:start_link/1</c></seemfa>.
    The pid of its server can be obtained with
    <seemfa marker="reltool#start_link/1"><c>reltool:get_server/1</c></seemfa>
    </p>
