-- Abstract     :  
-- The HELP System is a collection of programs which provide an interactive
-- online documentation facility.  Data for the facility is prepared as
-- a conventional text file which is formatted in an outline form, as follows:
--
--	0 Topic-Name
--		<text of topic>
--	1 1st-Level-Subtopic
--		<text of subtopic>
--	...
--	9 9th-Level-Subtopic
--		<text>
--	1 2nd-1st-Level-Subtopic
--		<text>
--	...
--	1 3rd-1st-Level-Subtopic
--	...
--	0 Next-Topic
--	...
--
-- The level numbers do not have to be consecutive, and the lower the
-- level number is, the higher its entry appears in the hierarchy (level 4
-- elements appear before level 6).  There may be as many topics at each
-- level as desired.  A line containing only a dot (.) character causes
-- a break between screens when the help file is displayed to the user:
--
--	this line appears on one screen
--	.
--	this line appears on the next screen (at the top)
--
-- The HELP System consists of three programs: HELP, HELP_BUILD, and
-- HELP_ANALYZE.
--
-- The HELP program is used to display information contained in a help file.
-- This information is in the form of a direct-access file created by the
-- HELP_BUILD program.  Briefly:
--
--		text of help file 
--			V
--		    HELP_BUILD
--			V
--		direct-access help file
--			V
--		HELP displays info to user
--
-- The HELP_ANALYZE program displays the structure hierarchy of a direct
-- access file which is created by HELP_BUILD.
