=head1 OPTIONS AND ARGUMENTS

=head2 General Options

=over 4

=item C<--verbose>

Requests informative output as processing proceeds. Can be repeated
to increase the amount of information.

=item C<--VERSION>

Shows the version number of the LaTeXML package..

=item C<--help>

Shows this help message.

=back

=head2 Source Options

=over 4

=item C<--sourcedirectory>=I<source>

Specifies the directory where the original latex source is located.
Unless latexmlpost is run from that directory, or it can be determined
from the xml filename, it may be necessary to specify this option in
order to find graphics and style files.

=item C<--validate>, C<--novalidate>

Enables (or disables) the validation of the source XML document (the default).

=back

=head2 Format Options

=over 4

=item C<--format>=C<(html|html5|html4|xhtml|xml)>

Specifies the output format for post processing.
By default, it will be guessed from the file extension of the destination
(if given), with html implying C<html5>, xhtml implying C<xhtml> and the
default being C<xml>, which you probably don't want.

The C<html5> format converts the material to html5 form with mathematics as MathML;
C<html5> supports SVG.
C<html4> format converts the material to the earlier html form, version 4,
and the mathematics to png images.
C<xhtml> format converts to xhtml and uses presentation MathML (after attempting
to parse the mathematics) for representing the math.  C<html5> similarly converts
math to presentation MathML. In these cases, any
graphics will be converted to web-friendly formats and/or copied to the
destination directory. If you simply specify C<html>, it will treat that as C<html5>.

For the default, C<xml>, the output is left in LaTeXML's internal xml,
but the math is parsed and converted to presentation MathML.
For html, html5 and xhtml, a default stylesheet is provided, but see
the C<--stylesheet> option.

=item C<--destination=>I<destination>

Specifies the destination file and directory.  The directory is needed for
mathimages, mathsvg and graphics processing.

=item C<--omitdoctype>, C<--noomitdoctype>

Omits (or includes) the document type declaration.
The default is to include it if the document model was based on a DTD.

=item C<--numbersections>, C<--nonumbersections>

Includes (default), or disables the inclusion of section, equation, etc,
numbers in the formatted document and crossreference links.

=item C<--stylesheet>=I<xslfile>

Requests the XSL transformation of the document using the given xslfile as stylesheet.
If the stylesheet is omitted, a `standard' one appropriate for the
format (html4, html5 or xhtml) will be used.

=item C<--css>=I<cssfile>

Adds I<cssfile> as a css stylesheet to be used in the transformed html/html5/xhtml.
Multiple stylesheets can be used; they are included in the html in the
order given, following the default C<ltx-LaTeXML.css> (unless C<--nodefaultcss>).
The stylesheet is copied to the destination directory, unless it is an absolute url.

Some stylesheets included in the distribution are
  --css=navbar-left   Puts a navigation bar on the left.
                      (default omits navbar)
  --css=navbar-right  Puts a navigation bar on the left.
  --css=theme-blue    A blue coloring theme for headings.
  --css=amsart        A style suitable for journal articles.

=item C<--javascript>=I<jsfile>

Includes a link to the javascript file I<jsfile>, to be used in the transformed html/html5/xhtml.
Multiple javascript files can be included; they are linked in the html in the order given.
The javascript file is copied to the destination directory, unless it is an absolute url.

=item C<--icon>=I<iconfile>

Copies I<iconfile> to the destination directory and sets up the linkage in
the transformed html/html5/xhtml to use that as the "favicon".

=item C<--nodefaultresources>

Disables the copying and inclusion of resources added by the binding files;
This includes CSS, javascript or other files.  This does not affect
resources explicitly requested by the C<--css> or C<--javascript> options.


=item C<--timestamp>=I<timestamp>

Provides a timestamp (typically a time and date) to be embedded in
the comments by the stock XSLT stylesheets.
If you don't supply a timestamp, the current time and date will be used.
(You can use C<--timestamp=0> to omit the timestamp).

=item C<--xsltparameter>=I<name>:I<value>

Passes parameters to the XSLT stylesheet.
See the manual or the stylesheet itself for available parameters.

=back

=head2 Site & Crossreferencing Options

=over 4

=item C<--split>, C<--nosplit>

Enables or disables (default) the splitting of documents into multiple `pages'.
If enabled, the the document will be split into sections, bibliography,
index and appendices (if any) by default, unless C<--splitpath> is specified.

=item C<--splitat=>I<unit>

Specifies what level of the document to split at. Should be one
of C<chapter>, C<section> (the default), C<subsection> or C<subsubsection>.
For more control, see C<--splitpath>.

=item C<--splitpath=>I<xpath>

Specifies an XPath expression to select nodes that will generate separate
pages. The default splitpath is
  //ltx:section | //ltx:bibliography | //ltx:appendix | //ltx:index

Specifying

  --splitpath="//ltx:section | //ltx:subsection
         | //ltx:bibliography | //ltx:appendix | //ltx:index"

would split the document at subsections as well as sections.

=item C<--splitnaming>=C<(id|idrelative|label|labelrelative)>

Specifies how to name the files for subdocuments created by splitting.
The values C<id> and C<label> simply use the id or label of the subdocument's
root node for it's filename.  C<idrelative> and C<labelrelative> use
the portion of the id or label that follows the parent document's
id or label. Furthermore, to impose structure and uniqueness, 
if a split document has children that are also split, that document
(and it's children) will be in a separate subdirectory with the
name index.

=item C<--scan>, C<--noscan>

Enables (default) or disables the scanning of documents for ids, labels,
references, indexmarks, etc, for use in filling in refs, cites, index and
so on.  It may be useful to disable when generating documents not based
on the LaTeXML doctype.

=item C<--crossref>, C<--nocrossref>

Enables (default) or disables the filling in of references, hrefs, etc
based on a previous scan (either from C<--scan>, or C<--dbfile>)
It may be useful to disable when generating documents not based
on the LaTeXML doctype.

=item C<--urlstyle>=C<(server|negotiated|file)>

This option determines the way that URLs within the documents
are formatted, depending on the way they are intended to be served.
The default, C<server>, eliminates unneccessary
trailing C<index.html>.  With C<negotiated>, the trailing
file extension (typically C<html> or C<xhtml>) are eliminated.
The scheme C<file> preserves complete (but relative) urls
so that the site can be browsed as files without any server.

=item C<--navigationtoc>=C<(context|none)>

Generates a table of contents in the navigation bar; default is C<none>.
The `context' style of TOC, is somewhat verbose and reveals more detail near the current
page; it is most suitable for navigation bars placed on the left or right.
Other styles of TOC should be developed and added here, such as a short form.

=item C<--index>, C<--noindex>

Enables (default) or disables the generation of an index from indexmarks
embedded within the document.  Enabling this has no effect unless
there is an index element in the document (generated by \printindex).

=item C<--splitindex>, C<--nosplitindex>

Enables or disables (default) the splitting of generated indexes
into separate pages per initial letter.

=item C<--bibliography=>I<pathname>

Specifies a bibliography generated from a BibTeX file
to be used to fill in a bibliography element.
Hand-written bibliographies placed in a C<thebibliography> environment
do not need this.  The option has no effect unless
there is an bibliography element in the document (generated by \bibliography).

Note that this option provides the bibliography to be used to
fill in the bibliography element (generated by C<\bibliography>);
latexmlpost does not (currently) directly process and format such a bibliography.

=item C<--splitbibliography>, C<--nosplitbibliography>

Enables or disables (default) the splitting of generated bibliographies
into separate pages per initial letter.

=item C<--prescan>

By default C<latexmlpost> processes a single document into one
(or more; see C<--split>) destination files in a single pass.
When generating a complicated site consisting of several documents
it may be advantageous to first scan through the documents
to extract and store (in C<dbfile>) cross-referencing data
(such as ids, titles, urls, and so on).
A later pass then has complete information allowing all documents
to reference each other, and also constructs an index and bibliography
that reflects the entire document set.  The same effect (though less efficient)
can be achieved by running C<latexmlpost> twice, provided a C<dbfile>
is specified.

=item C<--dbfile>I<=file>

Specifies a filename to use for the crossreferencing data when
using two-pass processing.  This file may reside in the intermediate
destination directory.

=item C<--sitedirectory=>I<dir>

Specifies the base directory of the overall web site.
Pathnames in the database are stored in a form relative
to this directory to make it more portable.

=back

=head2 Math Options

These options specify how math should be converted into other formats.
Multiple formats can be requested; how they will be combined
depends on the format and other options.

=over 4

=item C<--mathimages>, C<--nomathimages>

Requests or disables the conversion of math to images (png by default).
Conversion is the default for html4 format.

=item C<--mathsvg>, C<--nomathsvg>

Requests or disables the conversion of math to svg images.

=item C<--mathimagemagnification=>I<factor>

Specifies the magnification used for math images (both png and svg),
if they are made. Default is 1.75.

=item C<--presentationmathml>, C<--nopresentationmathml>

Requests or disables conversion of math to Presentation MathML.
Conversion is the default for xhtml and html5 formats.

=item C<--linelength>I<=number>

(Experimental) Line-breaks the generated Presentation
MathML so that it is no longer than I<number> `characters'.

=item C<--plane1>

Converts the content of Presentation MathML token elements to
the appropriate Unicode Plane-1 codepoints according to the selected font,
when applicable (the default).

=item C<--hackplane1>

Converts the content of Presentation MathML token elements to
the appropriate Unicode Plane-1 codepoints according to the selected font,
but only for the mathvariants double-struck, fraktur and script.
This gives support for current (as of August 2009) versions of
Firefox and MathPlayer, provided a sufficient set of fonts is available (eg. STIX).

=item C<--contentmathml>, C<--nocontentmathml>

Requests or disables conversion of math to Content MathML.
Conversion is disabled by default.
B<Note> that this conversion is only partially implemented.

=item C<--openmath>

Requests or disables conversion of math to OpenMath.
Conversion is disabled by default.
B<Note> that this conversion is only partially implemented.

=item C<--keepXMath>

By default, when any of the MathML or OpenMath conversions
are used, the intermediate math representation will be removed;
this option preserves it; it will be used as secondary parallel
markup, when it follows the options for other math representations.

=back

=head2 Graphics Options

=over 4

=item C<--graphicimages>, C<--nographicimages>

Enables (default) or disables the conversion of graphics
to web-appropriate format (png).

=item C<--graphicsmap=>I<sourcetype.desttype>

Specifies a mapping of graphics file types. Typically, graphics elements
specify a graphics file that will be converted to a more appropriate file
target format; for example, postscript files used for graphics with LaTeX
will be converted to png format for use on the web.  As with LaTeX,
when a graphics file is specified without a file type, the system will search
for the most appropriate target type file. 

When this option is used, it overrides I<and replaces> the defaults and provides
a mapping of I<sourcetype> to I<desttype>.  The option can be
repeated to provide several mappings, with the earlier formats preferred.
If the I<desttype> is omitted, it specifies copying files of type I<sourcetype>, unchanged.

The default settings is equivalent to having supplied the options:

  --graphicsmap=svg
  --graphicsmap=png
  --graphicsmap=gif
  --graphicsmap=jpg
  --graphicsmap=jpeg
  --graphicsmap=eps.png
  --graphicsmap=ps.png
  --graphicsmap=ai.png
  --graphicsmap=pdf.png

The first formats are preferred and used unchanged, while the latter
ones are converted to png.

=item C<--pictureimages>, C<--nopictureimages>

Enables (default) or disables the conversion of picture environments
and pstricks material into images.

=item C<--svg>, C<--nosvg>

Enables or disables (default) the conversion of picture environments
and pstricks material to SVG.
