+	  Libfastjson - A fast json library for C
+
+	  Libfastjson is a fork from json-c. The aim of this project
+	  is not to provide a slightly modified clone of json-c.
+	  Its aim is to provide:
+
+	  - a small library with essential json handling functions
+	  - sufficiently good json support (not 100% standards compliant)
+	  - be very fast in processing
