Config::Any provides a facility for Perl applications and libraries to
load configuration data from multiple different file formats. It sup-
ports XML, YAML, JSON, Apache-style configuration, Windows INI files,
and even Perl code.

The rationale for this module is as follows: Perl programs are deployed
on many different platforms and integrated with many different systems.
Systems administrators and end users may prefer different configuration
formats than the developers. The flexibility inherent in a multiple
format configuration loader allows different users to make different
choices, without generating extra work for the developers. As a devel-
oper you only need to learn a single interface to be able to use the
power of different configuration formats.
