19 * Library of internal classes and functions for module workshop
21 * All the workshop specific functions, needed to implement the module
22 * logic, should go to here. Instead of having bunch of function named
23 * workshop_something() taking the workshop instance as the first
24 * parameter, we use a class workshop that provides all methods.

38 * Full-featured workshop API
40 * This wraps the workshop database record with a set of methods that are called
41 * from the module itself. The class should be initialized right after you get
