Version? of getopt::Long

I'm giving tech support to someone and suspect his version od
GetOpt::Long is older than mine. What simple test can be given on the
command-line to determine what version is being used on his computer?
Perhaps something like:

perl -MAppConfig -e' print_version()'

or something along those lines...

Most Perl modules should have a package-level global variable called
$VERSION. So you can do this Perl one-liner to print the version:

perl -MSomePackage -e 'print "$SomePackage::VERSION\n";'
