support for using pandoc with citeproc

 The pandoc-citeproc library exports functions for using the citeproc
 system with pandoc. It relies on citeproc-hs, a library for rendering
 bibliographic reference citations into a variety of styles using a
 macro language called Citation Style Language (CSL). More details on
 CSL can be found here: http://citationstyles.org/ .

 This package provides a library for the Haskell programming language.
