It's the pod format of Perl documentation. Apart that, it is also used in ASCII contexts to visually mark code, but I generally avoid it here since whe have <code> tags anyway. In this situation, however, it seemed to me to be too be too short and confusing, so I added that pseudo-markup.

Title:
Use:  <p> text here (a paragraph) </p>

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
