Config::Any returns your configuration as a hash of hashes keyed by the name of the configuration file. This module merges these hashes into a single hash. If the "override" paramter is set to 0 in the paramters for "load_files" or "load_stems", configurations files later in the list can't override variables that are already set. The default is to override previously set variables. In all other regards Config::Any::Merge is a strict subclass of Config::Any and inherits all of its functions.
