|Blank lines separate paragraphs.
Text surrounded by asterisks is italicized. To get a literal
asterisk, use \* or **.
Text after a blank line that is indented by two or more spaces is
reproduced verbatim. (This is intended for code.)
Urls become links, except in the text field of a submission.
If your url gets linked incorrectly, put it in <angle brackets> and it should work.
