    <h3>Project Basics</h3>

    This project is aimed at using an swap file on our Linux systems. We want
    to be able to generate an RAM size dependant swap file in /var, instead of
    using an fixed sized swap partition. And automatically regenerate the swap
    file if RAM size changes, to fit the new size.
    <p>
    This project has produced an <a href="dphys-swapfile">dphys-swapfile</a>
    script for sizing, setting up and mounting an swap file. And an
    <a href="init.d.example">init.d script</a> that runs this script at boot
    and shutdown time.
    <p>
    This project was spawned from the
    <a href="http://nic.phys.ethz.ch/projects/dphys2/">dphys2</a> project
    (later replaced and made obsolete by the
    <a href="http://nic.phys.ethz.ch/projects/dphys3/">dphys3</a> project).

    <h3>Project Status</h3>

    For the full details of done/doing/todo of the project best read the
    <a href="Logfile">Logfile</a>. A short excerpt from it is here:
    <p>
    <h4>Done are:</h4>
    Milestone/Release 4 (2004.02.19):
    <ul>
      <li>This was still as part of
        <a href="http://nic.phys.ethz.ch/projects/dphys2/">dphys2</a>. Made
        <a href="dphys-swapfile">dphys-swapfile</a> script to automatically
        generate/resize and activate an swapfile, default 2*RAM size, and also
        deactivate and delete it at the approriate times</li>
    </ul>
    Milestone/Release 5 (2004.07.29):
    <ul>
      <li>Split out of dphys2 into an separate project, as this tool is
        also usefull without dphys2, on any Linux system</li>
      <li>Reworked as separate /sbin and /etc/init.d scripts</li>
    </ul>
    Milestone/Release 6 (2006.09.15):
    <ul>
      <li>Repackaged as separate non-debianised upstream for later
        debianisation by separate maintainer</li>
      <li>Slight code and documentation improvements</li>
    </ul>
    Milestone/Release 7 (2006.10.20):
    <ul>
      <li>Code and docs tidy up, extensive quoting improvements, no
        absolut paths in commands</li>
    </ul>
    Current (= development, = may be broken):
    <ul>
      <li>Nothing done</li>
    </ul>
    <h4>Todo are:</h4>
    <ul>
      <li>Nothing planned</li>
