Multi Layered Configuration
===========================

Yhis perl module is intended to help manage complex configuration situations.

Existing modules attempt to solve this problem by dictating the kind of
configuration files can be imported, and their locations.

This module works a little bit differently, in that it can define any number of
configuration "layers", which in practice, overlap each other so that
configurations set in "higher" levels obscure default values defined by lower
levels.

This provides te flixibility to allow simple or complex configuration of
anything from cli scripts to web applications.

The interface is fully object oriented - and may soon be moosified ;-)

Features:
---------

    Overlapping layers of configuration settings
    One-Layer per configuration source (file, URL, DB, ...)
    Observable changes to settings
    Layers can be individually reset and re-loaded without adverse side effects
    Debuggable (verbose dump shows source of each setting)
    Helps solve typical chicken/egg problem: configuration settings are built
        up in order of precedence, ie: command line first, user-specified config
        file, followed by user config, host config and default config

Goals:
------

    Get this CPAN clean
    Add useful features - remove useless ones

TODO:
-----

    convert all identifiers from camelCase to lower_case with underscores
    more test cases
    setup Makefile.PL etc. for CPAN
    remove included Notifications module - should rely on released Notifications module
        (ie: Notifications also needs publishing on CPAN!)

If you're thinking of forking this project, please let me know. It's based on
"my real world" experience, which may of course differ wildly from yours ;-)
