--html_code_style=...               off, inherit, or transparent: enable normal inline verbatim font where foreground and background color is inherited from the surroundnings. off, inherit and transparent are just synonyms for inheriting color from the text and make the background color transparent (use e.g. --html_code_style=inherit to avoid the red Boostrap color). Default: on (use the css-specified typesetting of <pre> tags). NOTE: the naming "html_code_style" is not optimal: it has nothing to do with code block style, but the <code> tag for inline verbatim text in the context of bootstrap css styles.
--html_pre_style=...                off, inherit, or transparent: let code blocks inside <pre> tags have foreground and background color inherited from the surroundnings. Default: on (use the css-specified typesetting of <pre> tags). This option is most relevant for Bootstrap styles to avoid white background in code blocks inside colorful admons.
--html_toc_indent=...               No of spaces for indentation of subsections in the table of contents in HTML output. Default: 3 (0 gives toc as nested list in Bootstrap-based styles).

--html_share=...                    Specify URL and there will be Facebook, Twitter, etc. buttons at the end of the HTML document. --html_share=https://mysite.com/specials shares on email, Facebook, Google+, LinkedIn, Twitter, and enables a print button too. --html_share=https://mysite.com/specials,twitter,facebook shares on Twitter and Facebook only. Sites are separated by comma. The following names are allowed: email, facebook, google+, linkedin, twitter, print.

--html_raw_github_url=...           URLs to files hosted on the doconce github account. Internet Explorer (and perhaps other browsers) will not show raw.github.com files. Instead on should use rawgit.com. For development of HTML sites in Safari and Chrome and can use rawgit.com. 
  Values of --html_raw_github_url=: safe or cdn.rawgit: use this for ready-made sites with potentially some traffic. The URL becomes https://cdn.rawgit.com/doconce/doconce/...
  test or rawgit: use this for test purposes and development with low traffic. The URL becomes https://rawgit.com/doconce/doconce/... 
  github or raw.github: the URL becomes https://raw.github.com and may fail to load properly.

--latex_admon=...                   Type of admonition in LaTeX: 
  colors1: (inspired by the NumPy User Guide) applies different colors for the different admons with an embedded icon; 
  colors2: like `colors1` but the text is wrapped around the icon; 
  mdfbox: rounded boxes with a optional title and no icon (default); 
  graybox2: box with square corners, gray background, and narrower than mdfbox, if code it reduces to something like mdfbox (mdframed based); the summary admon is in case of A4 format only half of the text width with text wrapped around (effective for proposals and articles); 
  grayicon: box with gray icons and a default light gray background; 
  yellowicon: box yellow icons and a default light yellow background; 
  paragraph:  plain paragraph with boldface heading. 
  Note: the colors in mdfbox and other boxes can customized.
--latex_admon_color=...             The color to be used as background in admonitions. A single value applies to all admons: either rgb tuple (--latex_admon_color=0.1,0.1,0.4) or saturated color('--latex_admon_color=yellow!5' - note the quotes needed for bash). 
  Multiple values can be assigned, one for each admon (all admons must be specified): '--latex_admon_color=warning:darkgreen!40!white;notice:darkgray!20!white;summary:tucorange!20!white;question:red!50!white;block:darkgreen!40!white'   If --latex_admon=mdfbox, the specification above with color1!X!color2 will automatically trigger 2*X as the background color of the frametitle.n  There are predefined multiple values, e.g., --latex_admon_color=colors1 gives red warnings, blue notice, orange questions, green summaries and yellow blocks, automatically adjusted with darker frametitles. 
  If --latex_admon=mdfbox, the background of the title and the color of the border of box can also be customized by direct editing. For example, a dark blue border and light blue title background is obtained by editing the .tex file as 
  doconce replace 'linecolor=black,' 'linecolor=darkblue,' mydoc.tex 
  doconce subst 'frametitlebackgroundcolor=.*?,' 'frametitlebackgroundcolor=blue!5,' mydoc.tex
  Actually, this particular (and common) edit is automatically done by the option --latex_admon_color=bluestyle
--latex_admon_color=yellowstyle (the latter has color yellow!5 instead and yellow!20 for the border)
--latex_admon_title_no_period       By default, a period is added to title admons that do not have a period, question mark, or similar. This option prevents adding a period such that the title acts like a heading.
--latex_admon_envir_map=...         Mapping of code envirs to new envir names inside admons, e.g., to get a different code typesetting inside admons. This is useful if admons have a special color and the color background of code blocks does not fit will with the color background inside admons. Then it is natural to use a different verbatim code style inside admons. If specifying a number, say 2, as in --latex_admon_envir_map=2, an envir like pycod gets the number appended: pycod2. One can then in --latex_code_style= or in doconce ptex2tex or ptex2tex specify the typesetting of pycod2 environments. Otherwise the specification must be a mapping for each envir that should be changed inside the admons: --latex_admon_envir_map=pycod-pycod_yellow,fpro-fpro2 (from-to,from-to,... syntax).
--latex_subex_header_postfix=...    Default: ). Gives headers a), b), etc. Can be set to period, colon, etc.
--xelatex                           Use xelatex instead of latex/pdflatex.
--latex_double_hyphen               Replace single dash - by double dash -- in LaTeX output. Somewhat intelligent, but may give unwanted edits. Use with great care!
--latex_elsevier_journal=...        Sets the journal name for the --latex_style=elsevier style. Default: none (no journal name).
--ipynb_split_pyshell=...           Split interactive sessions into multiple cells after each output. Applies to pyshell and ipy code environments. on, True, yes: split (default). off, False, no: do not split. Note that pyshell-t and ipy-t environments just displays the session, while default pyshell and ipy removes all output (all output from print statements will come after the entire session).
--ipynb_disable_mpl_inline          Disable automatic insertion of `%matplotlib inline` before the first import of matplotlib.
--ipynb_cite=...                    Typesetting of bibliography. plain: simple native typesetting (same as pandoc) (default); latex-plain: Similar to latex-style plain; latex: ipynb support for latex-style bibliographies (not mature).
--ipynb_admon=...

--ipynb_figure=...                  How to typeset figures in ipynb: md (plain Markdown syntax); imgtag (<img src="..." width=...> tag, default); Image (python cell with Image object).
--ipynb_movie=...                   How to typeset movies in ipynb: md (plain Markdown syntax, default); HTML: python cell with notebook `HTML` object containing the raw HTML code that is used in the DocOnce HTML format; ipynb: python cell with notebook `HTML` object with simple/standard ipynb HTML code for showing a YouTube or local video with a <video> tag.
--ipynb_non_editable_text           All text in a notebook is set to be uneditable. Code blocks are unchanged
--ipynb_non_editable_code           All codeblocks in a notebook is set to be uneditable

--examples_as_exercises             Treat examples of the form "==== Example: ..." as in exercise environments.
--exercises_as_subsections          Forces exercises to be typeset as subsections. Used to override various latex environments for exercises (esp. in Springer styles).
