I often need to find the version of different modules so I have come up with the small script to extract and print the $VERSION of a given module, since I am tired of writing one-liners to do it.
But I was wondering if there was a smarter way to get a module name, if the case where I just give a path to a .pm file? 
#!/usr/bin/perl -w

# $Id: version.pl,v 1.2 2003/05/14 19:44:28 jonasbn Exp $

use strict;

my $modulename = shift;

my $modulepath = $modulename;

if ($modulepath =~ m/::/) {
    $modulepath =~ s[::][/]g;
    require "$modulepath.pm";
} else {
    undef $/;
    open(FIN, "<", $modulepath) || die ("Unable to open file $modulepa
+th");
    my $module = <FIN>;
    close(FIN);
        
    ($modulename) = $module =~ m/package (.*);/;
    require "$modulepath";
}

my $str = '$'.$modulename.'::VERSION';
print "$modulename is version: ";
print eval($str); 
print "\n";
