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.
