-Fenced Code Extension for Python Markdown
-=========================================
-
-This extension adds Fenced Code Blocks to Python-Markdown.
-
-    >>> import markdown
-    >>> text = '''
-    ... A paragraph before a fenced code block:
-    ...
-    ... ~~~
-    ... Fenced code block
-    ... ~~~
-    ... '''
-    >>> html = markdown.markdown(text, extensions=['fenced_code'])
-    >>> print html
-    <p>A paragraph before a fenced code block:</p>
-    <pre><code>Fenced code block
-    </code></pre>
-
-Works with safe_mode also (we check this because we are using the HtmlStash):
-
-    >>> print markdown.markdown(text, extensions=['fenced_code'], safe_mode='replace')
-    <p>A paragraph before a fenced code block:</p>
-    <pre><code>Fenced code block
-    </code></pre>
-
-Include tilde's in a code block and wrap with blank lines:
-
-    >>> text = '''
-    ... ~~~~~~~~
-    ...
-    ... ~~~~
-    ... ~~~~~~~~'''
-    >>> print markdown.markdown(text, extensions=['fenced_code'])
-    <pre><code>
-    ~~~~
-    </code></pre>
-
-Language tags:
-
-    >>> text = '''
-    ... ~~~~{.python}
-    ... # Some python code
-    ... ~~~~'''
-    >>> print markdown.markdown(text, extensions=['fenced_code'])
-    <pre><code class="python"># Some python code
-    </code></pre>
-
-Optionally backticks instead of tildes as per how github's code block markdown is identified:
-
-    >>> text = '''
-    ... `````
-    ... # Arbitrary code
-    ... ~~~~~ # these tildes will not close the block
-    ... `````'''
-    >>> print markdown.markdown(text, extensions=['fenced_code'])
-    <pre><code># Arbitrary code
-    ~~~~~ # these tildes will not close the block
-    </code></pre>
