# UniValue
## Summary
A universal value class, with JSON encoding and decoding.
UniValue is an abstract data type that may be a null, boolean, string,
number, array container, or a key/value dictionary container, nested to
an arbitrary depth.
This class is aligned with the JSON standard, [RFC
7159](https://tools.ietf.org/html/rfc7159.html).
## Installation
This project is a standard GNU
[autotools](https://www.gnu.org/software/automake/manual/html_node/Autotools-Introduction.html)
project. Build and install instructions are available in the `INSTALL`
file provided with GNU autotools.
```
$ ./autogen.sh
$ ./configure
$ make
```
## Design
UniValue provides a single dynamic RAII C++ object class,
and minimizes template use (contra json_spirit).
