version.pl - extracts module data from installed and uninstalled modules

This script extracts module data from installed and uninstalled modules and script, targetting especially the version information.
The script takes either a module name (SEE SYNOPSIS), a path to a Perl module, script file or a directory.
The script looks for a package definition and a version variable.
The script is quite simple, the Module::Info::File and Mattia Barbon's Module::Info holds all the interesting stuff.
In the beginning I was using Module::Info, but due to a lacking functionality in this module I created Module::Info::File, which inherits from Module::Info and replaces the new_from_file method so the lacking data can be accessed. Apart from that you can use all the neat accessors from Module::Info.
The script gives to kinds of input depending on how it was called:
For single modules, module og script files:
<modulename> located in <directory location> is version: <versions number>
Test::More located in /System/Library/Perl/5.8.1 is version: 0.47
Or when called with a directory as argument (one line per located module):
<module name> <tab> <version number>
