I remember a friend doing this in a Tcl because it didn't have non-greedy quantifiers. (I wish I could remember the details... It was a very long time ago)

  • 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.
