Embed the V8 Javascript engine into Python.

> *Note: The initial purpose of this library is to render React components server side.*


## Compatibility

* GCC +4.8
* G++ +4.8
* Python 2.7, 3.4, 3.5 and PyPy 5.3

> *Note:* ***Linux-x64*** *is the only (officially) supported platform.
To build the binaries for other platforms, the `./dev` steps
must be adapted (probably to vagrant instead of docker) accordingly.
PRs are welcome.*


## Usage

```python
from v8cffi import shortcuts
shortcuts.set_up()

ctx = shortcuts.get_context()
ctx.load_libs(['./foo_bundled.js'])
ctx.run_script('foo.render("hola mundo");')
# "hola mundo"
```
