2015-07-19   Marc Green <marcgreen@cpan.org>
	* Release 3.30_1
	Simplified the detection of case-insensitivity in Pod::Simple::Search.

	Fixed "Use of uninitialized value $1 in lc" warning in
	Pod::Simple::Search.

	If @INC includes the current directory symbol, '.', the survey()
	method of Pod::Simple::Search no longer excludes it from its list
	of directories to search. Instead, The survey() and find() methods
	now both exclude duplicate directories from @INC (RT #102344).

	Moved source repository and updated links to new perl-pod GitHub
	organization: https://github.com/perl-pod/pod-simple.

	Improved repository links and added GitHub issue tracking link to
	the distribution metadata.

	Switched from File::Spec's catdir to catfile for path names, to
	fix failures on VMS. Also now use Unix path semantics where
	they're not required to be platform-specific. Thanks to Craig A.
	Berry for the patch (RT #105511).

	Improved the example use of the 'html_encode_chars()' method in
	the Pod::Simple::XHTML documentation. Patch from Randy Stauner.
