# As far as I understand, the copyright exists to make people create
bb4664
# more.  The copyright gives creators the legal power over their
bb4664
# creations and so the freedom to distribute them under the ethical
bb4664
# terms the creator considers better.  At this moment I don't feel
bb4664
# very confident about this legal affairs and their legal
bb4664
# implications, but I need to decide what copyright information the
bb4664
# centos-art.sh script will print out. So, in that sake, I'll assume
bb4664
# the same copyright information used by The CentOS Wiki
bb4664
# (http://wiki.centos.org/) as reference.
