+%description
+libfastjson is a fork from json-c, and is currently under development.
+The aim of this project is not to provide a slightly modified clone of json-c. It's aim is to provide:
+    1. a small library with essential json handling functions
+    2. sufficiently good json support (not 100% standards compliant)
+    3. be very fast in processing
