NAME:
   reconload
 PURPOSE:   (one line only)
 DESCRIPTION:
  The RECON data repository is scanned.  Files already in the database are
    not examined.  New entries into the database contain as much information
    as can be deduced at the start.  If the file names are properly
    constructed the UTdate will be set, otherwise left blank.  Many fields
    will require subsequent processing.
 CATEGORY:
