 * menhir, a O'Caml parser generator
   * Only for building Herodotos
 * menhirlib, the menhir runtime library (libmenhir-ocaml-dev)
 * PostgreSQL-ocaml library (libpostgresql-ocaml-dev)
 * XML-light (libxml-light-ocaml-dev)
 * Bolt (http://bolt.x9c.fr/) -- This needs camlp4-extra

 * ps2eps

 For conversion to PDF
=======================
 * pdftk
 * epstopdf

 For conversion to SVG images

 == Improvements ==

 * Native version of spatch (spatch.opt)
