NAME

Parrot::Configure::Step - Configuration Step Utilities

DESCRIPTION

The Parrot::Configure::Step module contains utility functions for steps to use.

Note that the actual configuration step itself is NOT an instance of this class, rather it is defined to be in the package Configure::Step. See docs/configuration.pod for more information on how to create new configuration steps.
