# Script to coordinate parsing of S. Chamberlain source-embedded 
# documentation markup language.

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