  <para os="i">By putting <filename class="directory">/tools/bin</filename> ahead
  of the standard <envar>PATH</envar>, all the programs installed in
  <xref linkend="chapter-temporary-tools"/> are picked up by the shell
  immediately after their installation. This, combined with turning off
  hashing, limits the risk that old programs from the host are being used
  when they should not be used any longer.</para>
