  -# Invoke asciidoctor-latex for LaTeX output by

  -#   asciidoctor-latex -a dialect=asciidoc foo.adoc
  -#   asciidoctor-latex -a dialect=manuscript foo.adoc
  -#   asciidoctor-latex -a dialect=latex foo.adoc

  -# Be sure to use XeLaTex for tex'ing
  -# For html output, use

  -#   asciidoctor-latex -a dialect=manuscript foo.adoc -b html
  -#   asciidoctor-latex -a dialect=latex foo.adoc -b html

  +new syntax with switches for three 'dialects'. See below.
  +
  +There are three dialects that you can set with the `:dialect` attribute:
  +
  +- `asciidoc`
  +- `asciidoc-manuscript`
  +- `asciidoc-latex`
  +
  +See the option flag `-a` to set the dialect from the command line. For example:
  +
  + $ asciidoctor-latex -a dialect=manuscript foo.adoc
  +
  +Be sure to use XeLaTex for tex'ing.
  +
  +To set the dialect with the Ruby API, use for example :
  +
  +----
  +      Asciidoctor.convert str, { 'dialect' => 'latex' }
  +----

positive.code: 
  == Commands
  
  Asciidoc math files can be rendered
  
  Render as HTML::
  Use `$ asciidoctor-latex -b html foo.adoc` to produce `foo.html`.
  
negative.code: 
  === Macro files
  
  The contents of a file named `macros.tex` will be
  read and used by `asciidoctor-latex`
  if it is in the same directory as the file
  being rendered.  This is the case regardless
