Net_PublicSuffix README
=======================
Net_PublicSuffix is a php class designed to facilitate access to the
public suffix list (see http://publicsuffix.org/).
Its primary interface is Net_PublicSuffix::registered_domain($d),
which determines the publicly registerable part of DNS label $d.
For example:
-------------------
require_once('Net/PublicSuffix.php');
$a = Net_PublicSuffix::registered_domain("www.example.com");
$b = Net_PublicSuffix::registered_domain("www.monkeys.example.co.uk");
// $a should be "example.com"
// $b should be "example.co.uk"
-------------------
Note that the module depends heavily on the existence of a local copy
of the public suffix list, which it assumes to be in the filesystem
at:
/usr/share/publicsuffix/public_suffix_list.dat
On debian systems, you should be able to get this by installing the
"publicsuffix" package.
I haven't yet bothered to get this module into PEAR properly. If
anyone wants to help do that, please let me know.
