   5 # Four passes:
   6 #       1) awk discards lines not intended for docn, and marks blocks of
   7 #          text with comments identifying source file;
   8 #       2) first sed pass interprets Chamberlain markup;
   9 #       3) second sed pass does cleanup that involves merging lines
  10 #       4) third sed pass does remaining cleans up---making {}
  11 #          printable within examples, and eliminating empty index entries and
  12 #          headings.
  13 #Third and second sed passes are separate because order of execution is hard
  14 #to control otherwise, making one or another of the things involving @example
  15 #inoperative.
