  23  this script use an $op to know what to do.
  24  if $op is empty or none of the above values,
  25         - the default screen is build (with all records, or filtered datas).
  26         - the   user can clic on add, modify or delete record.
  27  if $op=add_form
  28         - if primkey exists, this is a modification,so we read the $primkey record
  29         - builds the add/modify form
  30  if $op=add_validate
  31         - the user has just send datas, so we create/modify the record
  32  if $op=delete_form
  33         - we show the record having primkey=$primkey and ask for deletion validation form
  34  if $op=delete_confirm
  35         - we delete the record having primkey=$primkey
