    This module sets the values of $PageStartFmt and $PageEndFmt,
    used by various modules to generate output pages.  The general
    mechanism for page output is that a function such as HandleBrowse
    or HandleEdit will output the value of $PageStartFmt, followed
    by the action-specific content, followed by $PageEndFmt.  The
    HTML comment <!--PageText--> in the template file denotes the
    location where $PageStart ends and $PageEnd begins.  The
    HTML comment <!--HeaderText--> denotes where the contents of
    $HTMLHeaderFmt should be generated.

    The template file may also contain HTML comments of the form
    <!--PageHeaderFmt-->, <!--PageFooterFmt-->, etc.  These
    have the side effect of putting the strings that follow into
    the variables $PageHeaderFmt, $PageFooterFmt, etc. and then
    placing references to those variables into $PageStartFmt or 
    $PageEndFmt.  This allows HandleBrowse and other functions to
    selectively disable headers and footers by setting the corresponding
    variable to the empty string.

    Versions 0.6.1 and 0.6.2 made use of an $HTMLHeaders variable
    that is now deprecated, use <!--HeaderText--> and $HTMLHeaderFmt
    instead.
