Class::ObjectTemplate is a utility class to assist in the building of other Object Oriented Perl classes.

It was described in detail in the O\'Reilly book, \*(L"Advanced Perl Programming\*(R" by Sriram Srinivasam.

\s-1EXPORT\s0

attributes(@name_list)

This method creates a shared setter and getter methods for every name in the list. The method also creates the class constructor, \*(C`new()\*(C'.

\s-1WARNING\s0: This method must be invoked within the module for every class that inherits from Class::ObjectTemplate, even if that class defines no attributes. For a class defining no new attributes, it should invoke \*(C`attributes()\*(C' with no arguments.
