Upstream changes:
0.91 Sun 23 May 2010
	- Moving the FreeDesktop driver to prod
	- Adding File::HomeDir::Test driver

0.90_04 Fri 12 Feb 2010
	- Adding missing prereq

0.90_03 Tue  9 Feb 2010
	- Using FreeDesktop implementation only if xdg-user-script is
	  present, since it's now what's been used internally. This should
	  prevent test failures seen in _02. (JQUELIN)

0.90_02 Thu 14 Jan 2010
	- Adding support for the alternate FreeBSD xdg directory (JQUELIN)
	- Improved specification compliance (DAXIM)

0.90_01 Thu  7 Jan 2010
	- WARNING: This release introduces a major backwards incompatibility
	  for Unix users. The results returned by most methods may change.
	- Added complete implementation of the FreeDesktop specification and
	  auto-detection of the Unix hosts to which it applies (JQUELIN)
	- 01_compile.t now loads all backends (since on most platforms,
	  most backends will never normally be loaded).
