use Perl

Jim Brandt sent me a patch to my cpan(1) script so it could fetch the Changes file. While I was adjusting things to add that patch, I added a couple other things that I've always wanted. Here's teh new features in cpan-1.5:

Get the Changes file:

$ cpan -C Tie::Cycle
Revision history for Perl extension Tie::Cycle.
 
1.11 - Mon Jan  3 16:47:10 2005
* Previously, this module refused to work unless the input array had
more than one element.  What's the point of cycling otherwise?  I've
removed that restriction, though, because I shouldn't be the one who
gets to decide that.  A one element array should get a chance to act
like any other array.  It just happens to have one element.
 
1.09 - Thu Sep  2 19:56:41 2004
        * Just some distribution fixes.  No need to upgrade.
