+Em is a limited hypertext markup language.
+
+It is similar to Markdown, but it has a few key advantages:
+
+ 1. It is more readable.
+ 2. It is simpler to parse.
+ 3. There is *not* more than one way to do it (sorry Larry).
+
+Em takes plain-text readability seriously.  You should be able to
+write em in a plain-text e-mail message without the recipient noticing.
+
+Em is implemented as a portable awk script, whose simplicity speaks
+for the benefits of em.
+
+== Syntax ==
+
+=== Block-level formatting ===
+
+*A single empty line* always marks a block break.  There is
+no exception to this rule.  The line is removed in the final output.
+
+All blocks support inline formatting, except headings,
+preformatted blocks and terms in definition lists.
+
+One block cannot be put within another block.  For example,
+it is impossible to put a paragraph or a preformatted block
+inside a list item.  If you want paragraph lists, just use paragraphs:
+
+	1. Lorem ipsum dolor sit amet, consectetur adipiscing elit,
+	sed do eiusmod tempor incididunt ut labore et dolore
+	magna aliqua.
+
+	2. Ut enim ad minim veniam, quis nostrud exercitation
+	ullamco laboris nisi ut aliquip ex ea commodo consequat.
+
+==== Headings ====
+
+Headings begin and end with the same number of equal signs:
+
+	= First-level heading =
+	
+	== Second-level heading ==
+
+==== Lists ====
+
+Lists start with a single space.  There are four types of lists:
+
+	 - This is an unordered list
+	 - With two items
+	
+	 1. This is an ordered list
+	 2. With an item that spans
+	two lines
+	
+	 this is: a definition list
+
+	 [1] This is a reference list
+	 [2] With two items
+
+Unordered and ordered lists can be nested.  An additional space
+at the beginning of the line increases the item level by one:
+
+	 - First level
+	  - Second level
+	 - First level
+
+A reference list is a special type of list, unique to em.  It is a
+type of footnote list, to which you can make inline referencess
+like this:
+
+	See footnote [1].
+
+There is a special type of reference list item called a *hyperlink
+reference*.  It contains only a single word, without whitespace:
+
+	 [1] http://example.com
+
+Hyperlink reference items are removed in the final output,
+but you can still reference them inline:
+
+	You can download the file here [1].
+
+==== Preformatted blocks ====
+
+Preformatted blocks start with a single tab:
+
+		#include <stdio.h>
+		main() { puts("Hello world!\n"); }
+
+==== Paragraphs ====
+
+Paragraphs start with no space:
+
+	This is a paragraph
+	with two lines.
+
+	This is another paragraph.
+
+=== Inline formatting ===
+
+_Italic, bold and teletype text_ is marked with the asterisk,
+the underscore and the backtick, respectively:
+
+	Example of *italic* text.
+
+The marks are only valid in certain positions:
+
+ 1. At word borders
+ 2. After an opening parenthesis
+ 3. Before any of `.,:;?!)`
+ 4. Before a closing parenthesis any of `.,:;?!`
+
+_Inline references_ are created with square brackets:
+
+	Example of an inline reference [12].
+
+They are valid in positions 1, 3 and 4.
+
+When referencing a hyperlink reference (see above),
+the reference is replaced with a link.  For example:
+
+	It is available for download [1].
+	
+	 [1] v1.tgz
+
+translates into the following HTML:
+
+	<p>It is available for download (<a href="v1.tgz">link</a>).
+	</p>
+
+The default link text ("link") can be changed by setting
+the `linktext` environment variable.
