The class::container module facilitates building frameworks of several classes that inter-operate. it was first designed and built for html::mason, in which the compiler, lexer, interpreter, resolver, component, buffer, and several other objects must create each other transparently, passing the appropriate parameters to the right class, possibly substituting their own subclass for any of these objects.

the main features of class::container are:

* declaration of parameters used by each member in a class framework
* transparent passing of constructor parameters to the class that
needs them
* ability to create one (automatic) or many (manual) contained
objects automatically and transparently
