/*
** WEBPAGE: sitemap
**
** List some of the web pages offered by the Fossil web engine.  This
** page is intended as a supplement to the menu bar on the main screen.
** That is, this page is designed to hold links that are omitted from
** the main menu due to lack of space.
**
** Additional entries defined by the "sitemap-extra" setting are included
** in the sitemap.  "sitemap-extra" should be a TCL script with three
** values per entry:
**
**    *    The displayed text
**
**    *    The URL
**
**    *    A "capexpr" expression that determines whether or not to include
**         the entry based on user capabilities.  "*" means always include
**         the entry and "{}" means never.
**
** If the "e=1" query parameter is present, then the standard content
** is omitted and only the sitemap-extra content is shown.  If "e=2" is
** present, then only the standard content is shown and sitemap-extra
** content is omitted.
**
** If the "popup" query parameter is present and this is a POST request
** from the same origin, then the normal HTML header and footer information
** is omitted and the HTML text returned is just a raw "<ul>...</ul>".
