# Run this program. Successful tests will print as "."
# Unsuccessful tests will display the address and 
# whether it should have been declared correct or not.

# NB When using any of these REs, the candidate string should be stripped of white space
# and also of any /## subnet mask

# Thanks to the following:

# Stephen Ryan, Dartware, for starting this project 
#	http://forums.dartware.com/viewtopic.php?t=452
# Christoph Petschnig for a Ruby implementation of the same 
#	http://gist.github.com/294476
# Aeron for a shorter RE, and for Java and Ruby RE's 
#	(NB The RE does not always ignore whitespace before or after the IPv6 address)
# Phil Pennock who submitted a RE generated automatically from the full grammar in RFC3986 
#	http://people.spodhuis.org/phil.pennock/software/emit_ipv6_regexp-0.304
# Salvador Fandiño García who provides the CPAN module Regexp::IPv6 at
#	http://search.cpan.org/~salva/Regexp-IPv6-0.03/lib/Regexp/IPv6.pm

# Updated 26-27 Apr 2010 to use improved/fixed aeron RE
# Updated 22 Oct 2010 to add test cases from crisp
# Updated 26 May 2011 Factored to test all RE's each time; 
#                     Added tests for combinations of "0" and "::"
#                     Removed test strings with whitespace
