/** construct an output page in HTML
*
* This constructs a full HTML-page, starting at the DTD
* and ending with the html closing tag.
*
* This routine returns a full HTML-page, including a navigation
* menu and a footer with links to printer friendly version + logout.
* If the page is called with print=1 as one of the get-parameters, the
* background and navigation menu are suppressed by including the
* additional print.css stylesheet (configurable).
* This more or less allows for making a clean print of only the content.
* This additional stylesheet is added only once, even if this routine is
* called more than once (shouldn't happen). This stylesheet is configurable
* just like the regular stylesheet.
*
* Suppressing the background image (for printing) involves NOT generating
* the container div with id="page", or rather: we use a different id when
* viewed in regulare mode (id="page") or when viewed in print mode
* (id="print"). This allows for different tricks in print.css and at the
* very least allows for suppressing the background image.
*
* @return string complete HTML-page, ready for output

/** emergency exit of program in case there is something really, really wrong
*
* This routine outputs a short message and a 'cryptic' condition code
* and exits the program. It is called when something goes horribly wrong
* during the early stages of running the program, e.g. the database cannot
* be opened or there is a version mismatch between the program code (the
* .php-files) and the database. The complete condition code is the WAS
* release number followed by a slash followed by the WAS version number
* followed by a slash and the bare condition code. The message ends with
* a link to about.html with 'Powered by' or 'Based on', depending on the
* WAS original flag. Note that we try to show graphics (including logo) but
* that we switch back to text-only if it is too early, ie.
* before {@link waslib.php} is included.
*
* Here is an overview of meaning of the condition codes used.
*
* - 010: cannot find config.php, is W@S installed at all?
* - 015: cannot find program/main_XXXXX.php, is W@S installed at all?
* - 017: cannot calculate wasentry_script_name, are we being tricked?
* - 020: configuration error, invalid database type
* - 030: cannot connect to database, busy or configuration error?
* - 040: error accessing the database, is W@S installed at all?
* - 050: version mismatch, update to new version necessary
* - 060: magic_quotes_sybase is On
* - 070: there is no (default) node available in this (default) area
* - 080: there is no area available
* - 090: there is no valid theme available
*
* The condition code is numeric because it is easier to report for
* non-English speaking users than a complicated English sentence.
* (The language files are not yet loaded when error_exit() is called).
*
* @param string the bare condition code to report
* @param string the title to show in the generated HTML-page
* @return void this function never returns
* @uses WAS_VERSION indicate internal version in 'cryptic' message
* @uses $CFG
* @todo do we really want to 'leak' a link to the main site?
