PHPNuke 의 라이센스

PHPNuke를 받아다가 이리저리 보는데 INSTALL 파일에 이상한 문구가 있더군요.

# IMPORTANT: I saw many sites that removes the copyright line in the footer  #
# of each page. YOU'RE NOT ALLOWED TO REMOVE NOR CHANGE/EDIT THAT NOTE. If I #
# still see this problem happening I'll need to take extreme measures that   #
# can include: to change the PHP-Nuke license, to encrypt some parts of the  #
# code, stop distributing it for free and in an extreme case stop developing #
# it. The decision is in your hands.                                         #
# You can sell service based on PHP-Nuke, you can make money from it, you    #
# can do almost whatever you want with PHP-Nuke but DO NOT REMOVE NOR EDIT   #
# THE COPYRIGHT NOTICES!!! Fair Play.                                        #
# If you do not agree with this simple rule, delete all PHP-Nuke files       #
# rigth now and move away from it. Thanks.                                   #
