If you'd like to discover the module versions that you have installed, you can use a quick command line (among hundreds of other ways):

$ perl -MCGI -le 'print CGI->VERSION' # prints:  3.04

Is there a similar trick for scripts installed from CPAN, such as cpan itself?

I ask because I just installed the latest Bundle::CPAN distro and, when I called perldoc -m cpan, I saw this:

# $Id: cpan,v 1.5 2005/12/24 00:59:08 comdog Exp $
[download]

... which leads me to believe that this is version 1.5, not version 1.05 as you suggest farther down in your posting.

(Or is this an artifact of the way you set your $VERSION?

my $VERSION =
    sprintf "%d.%02d", q$Revision: 296 $ =~ m/ (\d+) \. (\d+) /xg;
