Modules
Modules are collections of code that you can include in your static web pages with the use of tags. CoolBrew modules are equivalent to CodeIgniter applications, but while CodeIgniter is generally intended to run one application, CoolBrew is intended to give you access to as many modules as you would like.
Structually, modules are the same as CodeIgniter applications. They consist of controllers containing methods, but instead of those methods representing pages as they do in CodeIgniter, they represent tags in CoolBrew.
The module can contain everything that a CodeIgniter application can, including libraries, hooks, module-specific config files, views, plugins and all the rest. In addition, CoolBrew modules can contain default JavaScript and CSS files that can be overridden at the system and document levels.
