=begin
  Lump is a simple content management system -- *very* simple.  Simplicity is
  one of its project goals, in fact.  The ultimate goal is to have as little
  markup embedded code as reasonably possible, and put as much as reasonably
  possible into a library (probably one class, maybe two classes tops).
