+
+    This is the second paragraph in the second item in the list.
+    The blank line above this paragraph is required.  The left edge
+    of this paragraph lines up with the paragraph above, both
+    indented relative to the bullet.
+
+    - This is a sublist.  The bullet lines up with the left edge of
+      the text blocks above.  A sublist is a new list so requires a

+    原始文本块内的任何标记都不会被转换，随便写。

+
+    这还会显示在原始文本块中。
+
+        缩进都会原样显示出来。
+
+        只要最后有空行，缩进退回到 :: 的位置，就表示退出了\ `原始文本块`_。
+
+会自动把网址转成超链接，像这样 http://www.bary.com/ ，注意结束的地方要跟空格。
+
+如果你希望网址和文本之间没有空格，可以用转义符号反斜杠 \\ 把空格消掉，由于反斜\
+杠是转义符号，所以如果你想在文中显示它，需要打两个反斜杠，也就是用反斜杠转义一\
+个反斜杠。
+
+渲染后紧挨文本和句号的超链接\ http://www.bary.com/\ 。
+
+其实遇到紧跟常用的标点的情况时，不需要用空格，只是统一使用空格记忆负担小。\
+你看\ http://www.bary.com/，这样也行。
+
+.. note::
+
+  写完本文我发现我用的渲染器对中文自动消除了空格，行尾不加反斜杠也行，但我不\
+  保证其他渲染器也这么智能，所以原样保留了文内的反斜杠。
+
+如果希望硬断行且不自动添加空格（例如中文文章），在行尾添加一个反斜杠。\
+折上去的部分就不会有空格。注意所有的硬换行都要对齐缩进。
