1.1.1.1 Section Title

That's it, the text just above this line.

1.1.1.2 Transitions

Here's a transition:

It divides the section.

1.1.2.1 Paragraphs

A paragraph.

1.1.2.2 Bullet Lists

• A bullet list

  • Nested bullet list.

  • Nested item 2.

• Item 2.

  Paragraph 2 of item 2.

  • Nested bullet list.

  • Nested item 2.

    • Third level.

    • Item 2.

  • Nested item 3.

1.1.2.3 Enumerated Lists

1. Arabic numerals.

   1. lower alpha)

      1. (lower roman)

         1. upper alpha.

            1. upper roman)

2. Lists that don't start at 1:

   3. Three

   4. Four

   3. C

   4. D

   3. iii

   4. iv

3. List items may also be auto-enumerated.

1.1.2.4 Definition Lists

Term

Termclassifier

1.1.2.5 Field Lists

what

Field lists map field names to field bodies, like database records. They are often part of an extension syntax. They are an unambiguous variant of RFC 2822 fields.

how arg1 arg2

The field marker is a colon, the field name, and a colon.

The field body may contain one or more body elements, indented relative to the field marker.

1.1.2.6 Option Lists

For listing command-line options:

-a

command-line option "a"

-b file

options can have arguments and long descriptions

--long

options can be long also

--input=file

long options can also have arguments

--very-long-option

The description can also start on the next line.

The description may contain multiple body elements, regardless of where it starts.

-x, -y, -z

Multiple options are an "option group".

-v, --verbose

Commonly-seen: short & long options.

-1 file, --one=file, --two file

Multiple options with arguments.

/V

DOS/VMS-style options too

There must be at least two spaces between the option and the description.

1.1.2.7 Literal Blocks

Literal blocks are indicated with a double-colon ("::") at the end of the preceding paragraph (over there -->). They can be indented:

if literal_block:
    text = 'is left as-is'
    spaces_and_linebreaks = 'are preserved'
    markup_processing = None

Or they can be quoted without indentation:

>> Great idea!
>
> Why didn't I think of that?

1.1.2.8 Line Blocks

Take it away, Eric the Orchestra Leader!

A one, two, a one two three four

Half a bee, philosophically,

must, ipso facto, half not be.

But half the bee has got to be,

vis a vis its entity. D'you see?

But can a bee be said to be

or not to be an entire bee,

when half the bee is not a bee,

due to some ancient injury?

Singing...

1.1.2.9 Block Quotes

Block quotes consist of indented body elements:

My theory by A. Elk. Brackets Miss, brackets. This theory goes as follows and begins now. All brontosauruses are thin at one end, much much thicker in the middle and then thin again at the far end. That is my theory, it is mine, and belongs to me and I own it, and what it is too.

—Anne Elk (Miss)

1.1.2.10 Doctest Blocks

>>> print 'Python-specific usage examples; begun with ">>>"'
Python-specific usage examples; begun with ">>>"
>>> print '(cut and pasted from interactive Python sessions)'
(cut and pasted from interactive Python sessions)

1.1.2.11 Tables

Here's a grid table followed by a simple table:

1.1.2.12 Footnotes

1(1,2)

A footnote contains body elements, consistently indented by at least 3 spaces.

This is the footnote's second paragraph.

2(1,2)

Footnotes may be numbered, either manually (as in 1) or automatically using a "#"-prefixed label. This footnote has a label so it can be referred to from multiple places, both as a footnote reference (2) and as a hyperlink reference (label).

3

This footnote is numbered automatically and anonymously using a label of "#" only.

*

Footnotes may also use symbols, specified with a "*" label. Here's a reference to the next footnote: †.

†

This footnote shows the next symbol in the sequence.

4

Here's an unreferenced footnote, with a reference to a nonexistent footnote: [5]_.

1.1.2.13 Citations

CIT2002(1,2)

Citations are text-labeled footnotes. They may be rendered separately and differently from footnotes.

Here's a reference to the above, [CIT2002], and a [nonexistent]_ citation.

1.1.2.14 Targets

This paragraph is pointed to by the explicit "example" target. A reference can be found under Inline Markup, above. Inline hyperlink targets are also possible.

Section headers are implicit targets, referred to by name. See Targets, which is a subsection of Body Elements.

Explicit external targets are interpolated into references such as "Python 5".

Targets may be indirect and anonymous. Thus this phrase may also refer to the Targets section.

Here's a `hyperlink reference without a target`_, which generates an error.

1.1.2.15 Directives

These are just a sample of the many reStructuredText Directives. For others, please see http://docutils.sourceforge.net/docs/ref/rst/directives.html.

1.1.2.15.2 Images

An image directive (also clickable -- a hyperlink reference):

A figure directive:

A figure is an image with a caption and/or a legend:

re	Revised, revisited, based on 're' module.
Structured	Structure-enhanced text, structuredtext.
Text	Well it is, isn't it?

This paragraph is also part of the legend.

1.1.3.2 Mathematics

For the discrete memoryless channel, Shannon's maximum channel capacity is:

where X and Y are random variable representing the input and output respectively. The optimization is taken all over the input probability distribution \(p = (p_1 \cdots p_n)\) with the constraints \(p_i \ge 0\)

and the mutual information is defined as:

The optimal \(p\) gives the distribution on the input symbol required to achieve the channel capacity.
