	Actually, it's done *outside* of SWISH-E.  The problem is
	simply: given a text or HTML file (regardless of how you

	Yes: see my Perl module bundled with the SWISH++ (beta)
	distribution.  My code correctly handles both HTML and plain
	text files, META elements, comments, ignores JavaScript, style
	sheets, and title text; also extracts text from ALT attrbutes
	of IMG and AREA elements.  It's also efficient (fast).
