'QQWry.Dat' the http://www.cz88.net/fox/ manpage is an IP file database. It
provides some useful infomation such as the geographical position of the
host bound with some IP address, the IP's owner, etc. the IP::QQWry manpage
provides a simple interface for this file database.

For more about the format of the database, take a look at this: the
http://lumaqq.linuxsir.org/article/qqwry_format_detail.html manpage

Caveat: The 'QQWry.Dat' database uses gbk or big5 encoding, 'IP::QQWry'
doesn't provide any encoding conversion utility, so if you want some other
encoding, you have to do it yourself. (BTW, the Encode manpage is a great
module for this.)
