    This script handles per-browser preferences.  Preference settings
    are stored in wiki pages as XLPage translations, and a cookie on
    the browser tells PmWiki where to find the browser's preferred
    settings.

    This script looks for a ?setprefs= request parameter (e.g., in
    a url); when it finds one it sets a 'setprefs' cookie on the browser 
    identifying the page to be used to load browser preferences,
    and loads the associated preferences.

    If there is no ?setprefs= request, then the script uses the
    'setprefs' cookie from the browser to load the preference settings.
