* Markdown

This wiki's pages are written in
[[http://pandoc.org][pandoc]]'s extended form of
[[http://daringfireball.net/projects/markdown][markdown]]. If you're not
familiar with markdown, you should start by looking at the
[[http://daringfireball.net/projects/markdown/basics][markdown "basics"
page]] and the
[[http://daringfireball.net/projects/markdown/syntax][markdown syntax
description]]. Consult the
[[http://pandoc.org/README.html][pandoc User's Guide]]
for information about pandoc's syntax for footnotes, tables, description
lists, and other elements not present in standard markdown.

Markdown is pretty intuitive, since it is based on email conventions.
Here are some examples to get you started:

#+BEGIN_HTML

For headings, prefix a line with one or more =#= signs: one for a major
heading, two for a subheading, three for a subsubheading. Be sure to
leave space before and after the heading.

** Wiki links

Links to other wiki pages are formed this way: =[Page Name]()=. (Gitit
converts markdown links with empty targets into wikilinks.)

To link to a wiki page using something else as the link text:
=[something else](Page Name)=.

Note that page names may contain spaces and some special characters.
They need not be CamelCase. CamelCase words are /not/ automatically
converted to wiki links.

Wiki pages may be organized into directories. So, if you have several
pages on wine, you may wish to organize them like so:

#+BEGIN_EXAMPLE
    Wine/Pinot Noir
    Wine/Burgundy
    Wine/Cabernet Sauvignon
#+END_EXAMPLE

Note that a wiki link =[Burgundy]()= that occurs inside the =Wine=
directory will link to =Wine/Burgundy=, and not to =Burgundy=. To link
to a top-level page called =Burgundy=, you'd have to use
=[Burgundy](/Burgundy)=.

To link to a directory listing for a subdirectory, use a trailing slash:
=[Wine/]()= will link to a listing of the =Wine= subdirectory.

    your system. Contact your administrator to request it.
