    <para os="a">We will cross-compile Vim so that we can have a text editor in
    <filename class="directory">/tools</filename>. Vim is not technically
    necessary in the temporary system, in that it is not there to satisfy any
    package dependencies in the final system, but we believe that a text editor
    is an extremely useful tool to have there.<!-- If you prefer a different
    editor, you may check the hints project at <ulink url="&hints-root;" />
    for information on cross-compiling other text editors. (placeholder - 
    uncomment this sentence if/when such information actually exists)--></para>

          if using a locale with a multibyte character set. This switch is

          Linux distributions like Fedora that use UTF-8 as a default
