// This is a core of the document system at nic.ua.net
//   looks for one of the sections at /source directory
//   and shows directory index or actuall file (if specified)
//   if shows directory, then includes top.php first and
//   bottom.php last.
//   Uses directory index from the /cache directory
//
// At this point the cached index is created manually. It is
//   in the plan for nearest future to generate cached directory 
//   index automatically, based on the control record within each 
//   document. Cache will be regenerated automatically if 
//   directory date is newer than the cached index file.
