Creating new sections
---------------------

To create a new section in the HWN, take the following steps:

  * In publish.hs:
    - Add an appropriate data type, and add a field of that type to
      the HWN record type.
    - Add the section to the output of the 'body' function in the
      desired location for the appropriate format types.
    - Make the new data type an instance of the Pretty class, defining
      the ppr function for whatever format types will be used.
    - add a clause to the 'tweak' function so that the new data type
      will be read properly from the content.wiki file.

  * In utils/totext.sh:
    - add a clause to the sed script so that the new section heading
      will be aligned to the left.
