-Citations
-=========
-
-Emacs org-mode lacks an official citation syntax, leading to
-multiple syntaxes coexisting. Pandoc recognizes four different
-syntaxes for citations.
-
-Citation support for org-mode is enabled by default. Support can
-be toggled off by disabling the `citation` extension; e.g.
-`pandoc --from=org-citations`.
-
-Berkeley-style citations
-------------------------
-
-The semi-official Org-mode citation syntax was designed by Richard
-Lawrence with additions by contributors on the [emacs-orgmode
-mailing list]. It is based on John MacFarlane's pandoc Markdown
-syntax. It's dubbed Berkeley syntax due the place of activity of
-its creators, both philosophers at UC Berkeley.
-
-### Simple in-text citation
-
-This is the simplest form of citation. It consists of the citation
-ID prefixed by '@'.
-
-Example:
-
-    @WatsonCrick1953 showed that DNA forms a double-helix.
-
-### In-text citation list
-
-Citations presented in the text unparenthesized are called
-*in-text citations*. The syntax for these citations is
-
-    [cite: PREFIX; INDIVIDUAL-REFERENCE; ... INDIVIDUAL-REFERENCE; SUFFIX]
-
-where the initial PREFIX and final SUFFIX are optional. At least
-one INDIVIDUAL-REFERENCE must be present. The colon and
-semicolons here are literal and indicate the end of the TAG and
-the end of a PREFIX or INDIVIDUAL-REFERENCE respectively.
-
-An INDIVIDUAL-REFERENCE has the format:
-
-    PREFIX KEY SUFFIX
-
-The KEY is obligatory, and the prefix and suffix are optional.
-
-A PREFIX or SUFFIX is arbitrary text (except `;`, `]`, and
-citation keys).
-
-Example:
-
-    [cite: See; @Mandelkern1981; and @Watson1953]
-
-### Parenthetical citation
-
-Citations surrounded by parentheses. The syntax is identical to
-in-text citations, except for the additional parentheses enclosing
-the initial `cite` tag.
-
-    [(cite): See; @Mandelkern1981; and @Watson1953]

-
-org-ref citations
------------------
-
-The [org-ref] package by [John Kitchen] is in wide use to handle
-citations and has excellent tooling support in Emacs. Its
-citation syntax is geared towards users in the natural sciences
-but still very flexible regardless.
-
-    cite:doe_john_2000
-    citep:doe_jane_1989
-    [[citep:Dominik201408][See page 20 of::, for example]]
-
-
-Pandoc-Markdown-like syntax
----------------------------
-
-Historically, Markdown-style citations syntax was the first that
-was added to pandoc's org reader. It is close to Markdown's
-citation syntax.
-
-Citations go inside square brackets and are separated by
-semicolons. Each citation must have a key, composed of '@' plus
-the citation identifier from the database, and may optionally
-have a prefix, a locator, and a suffix. The citation key must
-begin with a letter, digit, or `_`, and may contain
-alphanumerics, `_`, and internal punctuation characters
-(`:.#$%&-+?<>~/`). Here are some examples:
-
-### Simple citation
-
-The simplest method to insert a citation is to write the citation
-ID prefixed by '@'.
-
-
-Example:
-
-    [prefix @citekey suffix]
-    [see @doe2000 pp. 23-42]
-    [@doe2000 p. 5; to a lesser extend @doe2005]
-
-
-LaTeX-Syntax
-------------
-
-Use normal latex citation commands like `\cite{x}` or
-`\citet{y}`.
