+* Auxiliar routines for class hierarchy manipulation
+* LuaSocket toolkit (but completely independent of other LuaSocket modules)
+*
+* A LuaSocket class is a name associated with Lua metatables. A LuaSocket
+* group is a name associated with a class. A class can belong to any number
+* of groups. This module provides the functionality to:
+*
+*   - create new classes
+*   - add classes to groups
+*   - set the class of objects
+*   - check if an object belongs to a given class or group
+*   - get the userdata associated to objects
+*   - print objects in a pretty way
+*
+* LuaSocket class names follow the convention <module>{<class>}. Modules
+* can define any number of classes and groups. The module tcp.c, for
+* example, defines the classes tcp{master}, tcp{client} and tcp{server} and
+* the groups tcp{client,server} and tcp{any}. Module functions can then
+* perform type-checking on their arguments by either class or group.
+*
+* LuaSocket metatables define the __index metamethod as being a table. This
+* table has one field for each method supported by the class, and a field
+* "class" with the class name.
+*
+* The mapping from class name to the corresponding metatable and the
+* reverse mapping are done using lauxlib.
