-Config parser (used for bcoin).
-
-## Usage
-
-``` js
-const Config = require('bcfg');
-
-// Will consider ~/.my-module the prefix directory.
-const config = new Config('my-module', {
-  alias: {
-    'n': 'network'
-  }
-});
-
-// Inject some custom options first.
-config.inject({
-  some: 'user',
-  options: 'here'
-});
-
-config.load({
-  // Parse URL hash
-  hash: true,
-  // Parse querystring
-  query: true,
-  // Parse environment
-  env: true,
-  // Parse args
-  argv: true
-});
-
-// Will parse ~/.my-module/my-config.conf (throws on FS error).
-config.open('my-config.conf');
-
-// These will cast types and throw on incorrect type.
-console.log(config.str('username'));
-console.log(config.str('password'));
-console.log(config.uint('userid'));
-console.log(config.float('percent'));
-console.log(config.bool('initialize'));
