  29 /* About the name SwfdecBots:
  30  * We were (actually, we still are) looking for a good name to match
  31  * SwfdecBits, but couldn't come up with anything. So we just translated "bits"
  32  * as "Binary Input Token Stream", and as this struct is for output, the name
  33  * Bots == "Binary Output Token Stream" suddenly made a lot of sense.
  34  * If you find a more natural name, tell us.
