+description         JSON Spirit is a C++ library that reads and writes JSON files or streams.
+long_description    JSON is a text file format similar to XML, but less verbose. It has been\
+                    called XML lite. This article describes JSON Spirit, a C++ library\
+                    that reads and writes JSON files or streams. It is written using the\
+                    Boost Spirit parser generator. If you are already using Boost, you can\
+                    use JSON Spirit without any additional dependencies.
