   3     MoinMoin - Plain Text Parser, fallback for text/*
   4 
   5     You can supply format_args like this:
   6     {{{#!text cssclass1/cssclass2,<show_num>
   7     ...
   8     }}}
   9     The css classes are used for a wrapping div (same way as wiki parser does
  10     it).
  11     If show_num is 1, we use the code_area formatter and you will be able to
  12     toggle the line numbers by some javascript toggling link.
