+The subtitle, date, and tags lines are optional.
+
The date line may be written without a time:
2 Jan 2006
In this case, the time will be interpreted as 10am UTC on that date.
+The tags line is a comma-separated list of tags that may be used to categorize
+the document.
+
The author section may contain a mixture of text, twitter names, and links.
For slide presentations, only the plain text lines will be displayed on the
first slide.
