This is a model for GitBook plugins.

A plugin for GitBook is a node package that can be published on NPM. It has to follow the name convention: gitbook-plugin-*name*.

The package name should begin with gitbook-plugin-.

Examples: gitbook-plugin-mixpanel, gitbook-plugin-googleanalytics.

The package.json should contain a engine field using the standard norm.

"engines": {
    "gitbook": "*"
}

For example if you want your plugin to supports only GitBook version supperior to 0.3.1:

"engines": {
    "gitbook": ">=0.3.1"
}

The plugin entry point should return an object with some metadata.
