USAGE:	GutenMark [Options] [InputTxtFile [OutputHtmlFile]]
If the output file and/or input file are missing,  then the standard
output and/or input are used.  The available options are:
	"--author=name"  Overrides the name of the author, as
	                 deduced from the input file, with a
	                 string of your own choosing.  The
	                 quotes are usually necessary to
	                 compensate for blanks within the name.
	--caps-ok        Normally, ALL-CAPS phrases are converted
	                 automatically to italicized phrases.  The
	                 --caps-ok switch can be used to override 
	                 this behavior if, for example, you happen
	                 to know that emphasis is provided by
	                 _underscoring_ or by some other supported
	                 technique in the input text.
	--config=path    Path to non-default CFG file.
	--debug          Create optional logfiles.
	--first-capital  1st word of chapter can be ALL-CAPs
	--first-italics  1st word of chapter can be italics
	--force-neural   Uses the neural-net method for identifying
	                 headings, verse, paragraphs, etc.
	                 Cannot be used with --force-rule.
	--force-numeric  (Default.) Makes HTML entities numeric.
	--force-rule     (Default.) Uses rule-based method
	                 for identifying headings, verse, etc.
	                 Cannot be used with --force-neural.
	--force-symbolic Makes HTML entities symbolic.
	--help           Displays this information.
	--latex          Output LaTeX instead of html.
	--latex-sections In LaTeX, use section* rather
	                 than chapter*.
	--mdash-size=N   In LaTeX, allows the width of an
	                 mdash to be adjusted.  The default
	                 is 3.
	--neural-learn   Put neural net into learning mode.
	                 Implies --force-neural.
	--no-diacritical Turn off restoration of diacritical
	                 marks.  (On by default.)
	--no-foreign     Turn off automatic italicizing of
	                 foreign text.  (On by default.)
	--no-justify     Allows ragged right margin.
	                 Default is justified.
	--no-mdash       Keeps strings of dashes intact.
	                 Default converts to mdashes/ndashes.
	--no-parskip     Used with --latex only.  Allows LaTeX
	                 to indent paragraphs.  (The default
	                 behavior is unindented paragraphs 
	                 separated by blank lines.
	--no-prefatory   Adds invisible comments to the HTML
	                 that allow post-processing by the html2ps
	                 program to remove the prefatory area.
	                 (Still appears in the HTML, though.)
	--no-toc         By default, a table of contents is
	                 added to LaTeX output.  This switch
	                 removes the table of contents.
	--page-breaks    Adds invisible comments to the HTML
	                 that allow post-processing by the html2ps
	                 to add page breaks before headings.
	                 (HTML browses the same, though.)
	--profile=xxx    Select language xxx.  Actually, these
	                 names refer not to languages, but rather
	                 to names of profiles in GutenMark.cfg.
	                 But the profiles are usually named for
	                 a particular language.
	--single-space   Allow single space between sentences.
	"--title=name"   Overrides the book's title, as
	                 deduced from the input file, with a
	                 string of your own choosing.  The
	                 quotes are usually necessary to
	                 compensate for blanks within the name.
	                 If the title itself contains quotes,
	                 use single-quotes instead.
	--xml            Allow XML output (experimental only).
	--yes-header     Causes PG file-header to be retained.
	--ron            Activates various customizations that I (RSB)
	                 like.  Includes --latex --no-parskip --mdash-size=4.
	                 (Also, sets the page size to 5.5x8.5 inches,
	                 font to 12pt. New Century Schoolbook, and other
	                 stuff that GutenMark otherwise cannot affect.)
