It's called "version".
http://search.cpan.org/dist/version/
It allows this syntax:
our $VERSION = version->new(qw$Revision: 1.10 $);
And it doesn't work for the comparisons. It'll import a CVS tag, but it still
thinks 1.2 > 1.10.
No, it doesn't:
% perl -Mversion -le 'print version->new(qw$ Revision 1.2$) > version->new(qw$ Revision 1.10$)'
% perl -Mversion -le 'print version->new(qw$ Revision 1.10$) > version->new(qw$ Revision 1.2$)'
