  <para>
   <function>svn_log</function> returns the complete history of the item at the repository URL
   <parameter>repos_url</parameter>, or the history of a specific revision
   if <parameter>start_revision</parameter> is set. This function is equivalent
   to <userinput>svn log --verbose -r $start_revision $repos_url</userinput>.
  </para>
  <warning>
   <para>
    For repositories with large histories, the output may
    be quite large (one array item for every revision of the item).
    This function does not support the
    <userinput>--limit NUM</userinput> flag, nor does it support revision
    ranges (<userinput>start_revision</userinput> must be an integer).
