Update 2.20 to 2.22
-------------------
2.22  Tue Feb 17 08:32:00 2015
        - Fix licence info in Makefile.PL to say Perl.

2.21  Mon Feb 16 08:59:00 2015
        - Patch Makefile.PL to refer to the current repo, which is on
                github, and not the original one, which is on Adam's web
                site. See RT#102125.
        - Remove Build.PL because Karen Etheridge tells me Module::Build is
                no longer in core.  See RT#102126.
        - Edit line lengths in this file to a max of 100 chars.
        - Edit line lengths in the docs the same way.
        - Expand the See Also section of the docs.
