Initial import (perl-Module-Implementation-0.03-3)
    
    This module abstracts out the process of choosing one of several underlying
    implementations for a module. This can be used to provide XS and pure Perl
    implementations of a module, or it could be used to load an implementation
    for a given OS or any other case of needing to provide multiple
    implementations.
    
    This module is only useful when you know all the implementations ahead of
    time. If you want to load arbitrary implementations then you probably want
    something like a plugin system, not this module.
