The "/rptview" page:
Generate a report. The "rn" query parameter is the report number
corresponding to REPORTFMT.RN. If the "tablist" query parameter exists,
then the output consists of lines of tab-separated fields instead of
an HTML table.
Submenu of the /rptview page can be extended with additional hyperlinks by providing query parameter(s) of the form rvsmplXY=Z. Optional ending XY consists of a digit X from the set {1,2,3,4,5} and an optional letter Y that (if present) must be either 'a' or 's'. Mandatory Z is a repo-local hyperlink's target (wihout leading '/').
