  <p> <em> The popularity contest project is an attempt to map the usage of
  Debian packages.  This site publishes the statistics gathered from report
  sent by users of the <a

  package. This package sends every week the list of packages installed and the
  access time of relevant files to the server via email. Every day the server
  anonymizes the result and publishes this survey.
  For more information, read the <a href="${docurlbase}README">README</a> and the
