   7     This is a MoinMoin parser plugin that can display, nicely colored,
   8     the Gobby 3.0 or Sobby saved session, preserving the coloring.
   9 
  10     Note: The session file parser is extremely primitive and hacky, and
  11     probably doesn't include some special cases, as it was written in 5
  12     minutes while just looking at a sample session file.
  13 
  14     Also, the code was previously a standalone filter, and was later 
  15     wrapped in all the MoinMoin plugin stuff -- so it has its own function
  16     for quoting html, and generally is very dirty.
  17 
  18     But at least it's some start.
  19 
  20     This is public domain.
