   3     MoinMoin - Blockquote Parser
   4 
   5     Heavily inspired by Nir Soffer's marvelous Section Parser
   6 
   7     For proper functioning of the parser you need to install
   8     header.py in your MoinMoin/util directory, add some css
   9     formatter stuff to e.g. common.css and provide a
  10     translation for _('Source').
  11 
  12     Header.py is taken from Section Parser and modified for
  13     Blockquote Parser. For having more accessible layout fun
  14     do also install Section Parser which allows to have nice
  15     layout in a simple and maintainable way.
