 Simple tool for sending email with sendmail, postfix or ssmtpd.
 
 Example:
-{{{
+```python
-    import pysema
+import pysema
 
-    pysema.send(
+pysema.send(
-        ['alice@example.com', 'bob@example.com'],
+    ['alice@example.com', 'bob@example.com'],
-        'really good subject line',
+    'really good subject line',
-        'Message body goes here'
+    'Message body goes here'
-        )
+    )
-}}}
+```
 
 If you need to send some complex message, use [email.message][em] from the 
 Python standard library to construct the message (including header fields) and 
 pass it to the `send_message` function:
 
-{{{
+```python
-    import pysema
+import pysema
-    from email.message import EmailMessage
+from email.message import EmailMessage
 
-    msg = EmailMessage()
+msg = EmailMessage()
-    # compose message
+# compose message
 
-    pysema.send_message(msg)
+pysema.send_message(msg)
-}}}
+```
 
 if something goes whoopsie a `pysema.SendMailException` is raised.
