+This library adds CommonJS module support to Sprockets via Browserify.  It lets
+you mix and match //= require directives and require() calls for including plain
+javascript files as well as modules.
+
+Provided capabilities:
+
+ - Manage JS modules with npm
+ - Serve assets with Sprockets
+ - Require modules with require() (without separate //= require directives)
+ - Only build required modules
+ - Require npm modules in your Rails assets
+ - Require modules relative to asset paths (i.e., app/assets/javascript) with
+   non-relative syntax
+ - Configure browserify options for each JavaScript file so you can mark modules
+   with --require, --external, etc.
