Multi-profile is a module to manage global configurations for multiple profiles.

## Installation

```sh
npm install multi-profile --save
```

## Usage

```js
var profile = require('multi-profile');
var data = {};
var p = profile({
  path: '~/.cortex',
  context: data,
  schema: {
    port: {
      value: 8888,
      type: {
        validator: function(v, key, attr) {
          if (v <= 9000) {
            attr.error('`port` must greater than 9000');
          }
          // If you've already called `attr.error`, it will be considered a failure,
          // which means it's not necessary to return a value
          return v > 9000;
        },
        setter: function(v, key, attr) {
          // `this` <=> `data`
          // The return value will set to the multi-profile instance.
          // And in the same time, we set `port` to `data`
          return this.port = v;
        },
        getter: function(v, key, attr) {
          return this.port || v;
        }
      }
    },

    rcfile: {
      value: '~/.bashrc'
    }
  }
});

// .init() method must be called before any invocations of other methods.
p.init();
```
