the GNTP PHP library comes in two flavors - one that uses PEAR and one
that does not. from the GNTP PHP page:
"Choose your version:
0.9.0b2 - if you have minimum PHP 4.3.0 and PEAR 1.5.4 installed.
Required also PEAR::Net_Socket 1.0.9
2.0.0RC1 - if you have minimum PHP 5.2.0 (PEAR is optional: uses
installer for a quick and simple installation)"
i didnt list the UDP library because there are already tons of Growl/
UDP libraries out there in lots of languages. the GNTP option offers a
lot more functionality, so i was just focusing on that. of course, GfW
supports the UDP protocol, so you are free to use any of the available
UDP libraries out there as well.
