Module::Versions handles versions of loaded modules with a flexible result
interface. The main goal is to get as much version informations as possible
about a module or module list with a simple call interface and an
absolutely flexible result interface. Module::Versions handles *loaded* and
*loadable* modules.

The motivation for writing this module was the need for better support
facilities to get informations about the used modules and versions in the
productivity environment. Module::Versions allows shipping applications
basically with something like a '-version' option (See the Getopt::Long
manpage) but with expanded functions.

Module::Versions tries to read the loaded/loadable module's $VERSION. For
extended purposes any private project 'version variables' can be fetched
($_VERSION, $version, $REV, etc.).
