Bug#618315: Acknowledgement (libsocket-getaddrinfo-perl: README.Debian misrepresents the nature of the bin/get{addr, name}info binaries)

[Nicholas Bamber]

Paul,
	Thanks for all the extra information. At the moment our intention is to 
incorporate all the extra information into README.Debian. The objection 
against putting these scripts into $PATH,
was that the names were not really clear enough. I think if we could 
change the names to "socket_getaddrinfo" and "socket_getnameinfo" it 
would go through.


	On an unrelated matter, as the author of IO::Socket::IP, I wonder if 
you have any insight into why IO::Socket::INET does not support IPv6.
