	# 1. delete first 8 lines of comments (1,8d)
	# Some sections have a comment block before the section
	#    [main] Put the comment block with the section marker
	#    after the index/code directives. To do this:
	# 2. Store all comment and blank lines in the hold space
	#    (H).  Delete the current line and continue with the
	#    next line (d).
	# 3. When we see a section marker, append the section
	#    marker to the hold space (H). substitute for the
	#    section marker index and code directives
	#    (s/.../.../) using the section name (\1) for the
	#    index. Print the directives (p). Empty (zero) the
	#    pattern space (z). Pull the hold space to the
	#    pattern space (x) (which also empties the hold space
	#    because of (z). Print the new pattern space
	#    [comments and section marker] (p). Delete the patern
	#    space and process next input line (d).
	# 4. For any other line, append the line to the hold
	#    space (H). Zero out the pattern buffer (z). Swap the
	#    hold space and pattern space [comments and setting
	#    line] (x).
	#
	#    Automatically print the pattern space after the last
	#    command because we are not using 'sed -n'.
	#
	# The last sed command indents every line that is not
	#   empty or does not start with '..' (a directive) with
	#   two spaces.
	# The cat -s squeezes adjacent blank lines to 1 blank
	#   line.
