module TPDB.Pretty

-- | The abstract data type <tt><a>Doc</a> ann</tt> represents pretty
--   documents that have been annotated with data of type <tt>ann</tt>.
--   
--   More specifically, a value of type <tt><a>Doc</a></tt> represents a
--   non-empty set of possible layouts of a document. The layout functions
--   select one of these possibilities, taking into account things like the
--   width of the output document.
--   
--   The annotation is an arbitrary piece of data associated with (part of)
--   a document. Annotations may be used by the rendering backends in order
--   to display output differently, such as
--   
--   <ul>
--   <li>color information (e.g. when rendering to the terminal)</li>
--   <li>mouseover text (e.g. when rendering to rich HTML)</li>
--   <li>whether to show something or not (to allow simple or detailed
--   versions)</li>
--   </ul>
--   
--   The simplest way to display a <a>Doc</a> is via the <a>Show</a> class.
