# itk::Archetype
# ----------------------------------------------------------------------
# Base class for all widgets in the [incr Tk] Toolkit. Provides
# facilities to merge widget options into a composite list of options
# for the overall widget. Derived classes add widgets and methods to
# specialize behavior.
#
# METHODS:
# configure
# configure -option
# configure -option value ?-option value?...
# Used to set/query configuration options
#
# component
# component <name> <command> ?<arg> <arg>...?
# Invokes the given <command> as a method on the component
# called <name>.
#
# itk_component add <name> <create-cmd> <option-cmds>
# Creates a component widget and merges its options into
# the composite option list for the overall widget
#
# itk_component delete <name> ?<name>...?
# Destroys a component widget and removes its options from
# the composite option list
#
# itk_option add <name> ?<name>...?
# Adds the option <name> belonging to a class or component
# widget into the option list. Options can be added even
# if they were not originally kept when the component was
# created.
#
# itk_option remove <name> ?<name>...?
# Removes the option <name> belonging to a class or component
# widget from the option list. This allows a derived class
# to turn off or redefine undesirable options inherited from
# a base class.
#
# WIDGET ATTRIBUTES:
# none
