    (description "Pandoc is a powerful utility to transform various
input formats into a wide range of output formats.  To alter the
exported output document, Pandoc allows the usage of filters, which
are pipes that read a JSON serialization of the Pandoc AST from stdin,
transform it in some way, and write it to stdout.  It allows therefore
to alter the processing of Pandoc's supported input formats, for
instance one can add new syntax elements to markdown, etc.

This package provides Python bindings.")
