  33  *  should be added with void require(string const & name).
  34  *
  35  *  i.e require("amssymb")
  36  *
  37  *  To add support you should only need to require() the package name as
  38  *  packages which don't have special requirements are handled automatically.
  39  *  If your new package does need special consideration you'll need to alter
  40  *  string const getPackages() const;
  41  *  Remember to update the validate function in Buffer.cpp and Paragraph.cpp
  42  *  when you do so.
