Morpheus is a Perl module that implements a configuration engine that completely separates config consumers from config providers. Consumers can obtain configuration values by using this module or the morph script. Configuration values are bound to various nodes in the global configuration tree, similar to a virtual file system. Consumers can ask for any node or for any subtree. Providers are plugins which can populate the configuration tree from any sources, such as local configuration files, configuration database, and the environment. The overall program configuration is merged together from all data provided by plugins.
