This section lists various macros that can be used to modify the looks of your
document. When used, these macros must appear em(before) stating the document
type with tt(article), tt(report), tt(book), tt(manpage) or tt(plainhtml).
    itemization(
    it() tt(abstract(text)): This macro is relevant for all output formats.
The tt(text) is added to the document after the title, author and date
information, but before the table of contents. The abstract is usually set as
a quote, in italics font (though this depends on the output format).
Abstracts are supported in tt(article)s and tt(report)s, but not in other
document types. I.e., if you need introductory text in a tt(book), you should
start with a non-numbered chapter that holds this text.
    it() tt(affiliation(site)): This macro is relevant for tt(article),
tt(report) and tt(book) documents. It defines the affiliation of the
author. The tt(site) information appears in the title, below the author's
name.
    it() tt(htmlbodyopt(option)(value)): This macro adds tt(option="value") to
the tt(<body>) tag that is generated for HTML output. The HTML converter
generates tt(<body>) tags each time that a new file is started; i.e., at the
top of the document and at each chapter-file. Different HTML browsers support
different tt(<body>) tag options, but useful ones may be e.g.:
        verb(
    htmlbodyopt(fgcolor)(#000000)
    htmlbodyopt(bgcolor)(#FFFFFF)
        )
    This defines the foreground color as pure white (red/green/blue all 0) and
the background color as black (red/green/blue all hexadecimal FF, or 255).
Another useful option may be tt(htmlbodyopt(background) (some.gif)), defining
tt(some.gif) as the page background.
    
    See the documentation on HTML for more information.
    
    Note that tt(value) is automatically surrounded by double quotes when 
this macro is used. They should not be used by authors using this macro.
    it() tt(latexdocumentclass(class)): This macro forces the
    tt(\documentclass{...}) setting in LaTeX output to tt(class).
    it() tt(latexlayoutcmds(commands)): This macro can be used to specify your
own LaTeX layout commands. When present, the tt(commands) are placed in LaTeX
output following the tt(\documentclass) definition.
    it() tt(latexoptions(options)): This macro is only relevant for LaTeX
output formats, it is not expanded in other formats. The tt(options) are used
in LaTeX's tt(\documentclass) definition; e.g., a useful option might be
tt(dina4). Multiple options should be separate by commas, according to the
LaTeX convention.
    it() tt(latexpackage(options)(name)): This macro is only relevant for
LaTeX output formats, it is not expanded in other formats. Each em(package)
should have its own tt(latexpackage()) statement. If there are no options, the
tt(options) argument should remain empty. Here is an example using this macro:
        verb(
    latexpackage(dutch)(babel)
        )
    it() tt(mailto(email)): The tt(mailto) macro is only expanded in HTML
documents, it is ignored in other formats. It defines where mail about the
document should be sent to.
    it() tt(nosloppyhfuzz()): By default, the LaTeX output contains the text
        verb(
    \hfuzz=4pt
        )
    which is placed there by the macro package. This suppresses em(overfull
hbox) warnings of LaTeX when the overfull-ness is less than 4pt.  Use
tt(nosloppyhfuzz()) to get the standard LaTeX warnings about overfull hboxes.
    it() tt(notableofcontents()): As the name suggests, this macro suppresses
the generation of the table of contents. For HTML that means that no
clickable index of sections appears after the document title.

The table of contents is by default suppressed in tt(plainhtml) and
tt(manpage) documents.
    it() tt(notitleclearpage()): Normally, Yodl inserts a tt(clearpage())
directive after typesetting title information in tt(book) or tt(report)
documents, but not in tt(article) documents. Use tt(notitleclearpage) to
suppress this directive.
    it() tt(notocclearpage()) (no table-of-contents clear-page): In all
document types, Yodl inserts a tt(clearpage()) directive following the table
of contents. Use tt(notocclearpage()) to suppress that.
    it() tt(noxlatin()): The LaTeX output contains by default the command to
include the file tt(xlatin1.tex), distributed with Yodl. This file maps
Latin-1 characters to LaTeX-understandable codes and makes sure that you can
type characters such as tt(ü), and still make them processable by LaTeX. If
you don't want this, put tt(noxlatin()) in the preamble.
    it() tt(standardlayout()): This is another LaTeX option.  Use
tt(standardlayout()) to get `vanilla' LaTeX layout, possibly indenting
paragraphs and using fairly limited vertical spacing between paragraphs.
This macro is ignored for other conversion types.
    it() tt(titleclearpage()): Forces the insertion of a tt(clearpage())
directive after the title information has been typeset. This behavior is the
default in tt(book) and tt(report) documents. See also tt(notitleclearpage()).
    it() tt(tocclearpage()): Forces the insertion of a tt(clearpage())
directive following the table of contents. This behavior is default in all
document types; the macro is provided for consistency reasons with
tt((no)titleclearpage()).
    )
    em(Note again): these modifiers must appear em(before) the document type
definition.
