pkgsrc changes:
  - Updating package of p5 module Path::Class from 0.16nb1 to 0.17
  - Setting license to ${PERL5_LICENSE} according to META.yaml

Upstream changes:
 - dir(undef) now returns undef rather than the rootdir, because undef
   was probably a mistake by the caller, and the rootdir is too scary
   a default. [Suggested by John Goulah]

 - Temporary files during testing are now created in the system temp
   directory, rather than somewhere in t/ .  See RT #31382. [Suggested
   by Alex Page]

 - Added is_relative() as the obvious complement to the existing
   is_absolute() method.

 - Added a resolve() method to clean up paths much more thoroughly
   than cleanup(), e.g. resolving symlinks, collapsing foo/../bar
   sections, etc. [Suggested by David Garamond]

 - Fixed a problem in which a file/directory called "0" or \ 
"0.0" would
   end a loop prematurely when using the idiom 'while($x =
   $dir->next) {...}'.  See http://rt.cpan.org/Ticket/Display.html?id=29374
   [Spotted by Daniel Lo]

 - Fixed an exists($array[$i]) that prevented compatibility with perl
   5.005.

 - Moved the repository from my personal CVS repo to Google Code.
