If you are familiar with +Markdown or Textile, you will quickly grasp reStructuredText. The focus is +on readability, user friendliness, and an "I've got your hand, baby" feel. +While they can be quite technical, we always write for humans! + +A table of contents should always be included like the one below. +It is created automatically by inserting the ``.. contents::`` +directive on a line by itself. + +.. contents:: Page Contents + + +************** +Tools Required +************** + +To see the rendered HTML, ePub, PDF, etc., you will need to install Sphinx +along with the PHP domain extension for Sphinx. The underlying requirement +is to have Python installed. Lastly, you will install the CI Lexer for +Pygments, so that code blocks can be properly highlighted. + +.. code-block:: bash + + easy_install sphinx + easy_install sphinxcontrib-phpdomain + +Then follow the directions in the README file in the :samp:`cilexer` folder +inside the documentation repository to install the CI Lexer. + + + +***************************************** +Page and Section Headings and Subheadings +***************************************** + +Headings not only provide order and sections within a page, but they also +are used to automatically build both the page and document table of contents. +Headings are formed by using certain characters as underlines for a bit of +text. Major headings, like page titles and section headings also use +overlines. Other headings just use underlines, with the following hierarchy:: + + # with overline for page titles + * with overline for major sections + = for subsections + - for subsubsections + ^ for subsubsubsections + " for subsubsubsubsections (!) + +The :download:`TextMate ELDocs Bundle <./ELDocs.tmbundle.zip>` can help you +create these with the following tab triggers:: + + title-> + + ########## + Page Title + ########## + + sec-> + + ************* + Major Section + ************* + + sub-> + + Subsection + ========== + + sss-> + + SubSubSection + ------------- + + ssss-> + + SubSubSubSection + ^^^^^^^^^^^^^^^^ + + sssss-> + + SubSubSubSubSection (!) + """"""""""""""""""""""" + + + + +******************** +Method Documentation +******************** + +When documenting class methods for third party developers, Sphinx provides +directives to assist and keep things simple.
