-x-revision: 1
-Synopsis:            Types for representing a structured document
-Description:         @Text.Pandoc.Definition@ defines the 'Pandoc' data
-                     structure, which is used by pandoc to represent
-                     structured documents.  This module used to live
-                     in the pandoc package, but starting with pandoc 1.7, it
-                     has been split off, so that other packages can use it
-                     without drawing in all of pandoc's dependencies, and
-                     pandoc itself can depend on packages (like citeproc-hs)
-                     that use them.
-                     .
-                     @Text.Pandoc.Builder@ provides functions for building
-                     up @Pandoc@ structures programmatically.
-                     .
-                     @Text.Pandoc.Generic@ provides generic functions for
-                     manipulating Pandoc documents.
-                     .
-                     @Text.Pandoc.Walk@ provides faster, nongeneric functions
-                     for manipulating Pandoc documents.
-                     .
-                     @Text.Pandoc.JSON@ provides functions for serializing
-                     and deserializing a @Pandoc@ structure to and from JSON.
