+# bcfg
+
+Config parser (used for bcoin).
+
+## Usage
+
+``` js
+const bcfg = require('bcfg');
+
+const config = bcfg('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'));
