+Output the header of the page. This includes:
+ - The HTML header
+ - The H1/H3 stuff which includes the directory.
+
+ startpage($r, $uame, $udom, $thisdisfn);
+ $r - The apache request object.

+ $udom - Domain name the user is logged in under.
+ $thisdisfn - Displayable version of the filename.
+
+=item getTitleString($fullname)
+
+ Get the title string or "[untitled]" if the file has no title metadata:
+ Without the latter substitution, it's impossible to examine metadata for
+ untitled resources. Resources may be legitimately untitled, to prevent
+ searches from locating them.
+
+ $str = getTitleString($fullname);
+ $fullname - Fully qualified filename to check.

+ $r - Apache request object.
+ $reqfile - File in request.
+ $here - Where we are in directory tree.
+ $dirname - Name of directory special file.
+ $modtime - Encoded modification time.
