 gsub(r, s [, t])        For each substring matching the regular expres-
                               sion r in the string t, substitute  the  string
                               s,  and return the number of substitutions.  If
                               t is  not  supplied,  use  $0.   An  &  in  the
                           replacement text is replaced with the text that
                           was actually matched.  Use \& to get a  literal
                               &.   (This  must  be  typed as "\\&"; see GAWK:
