#   As far as I understand, the copyright exists to make people create
Alain Reguera Delgado 66223d
#   more.  The copyright gives creators the legal power over their
Alain Reguera Delgado 66223d
#   creations and so the freedom to distribute them under the ethical
Alain Reguera Delgado 66223d
#   terms the creator considers better.  At this moment I don't feel
Alain Reguera Delgado 66223d
#   very confident about this legal affairs and their legal
Alain Reguera Delgado 66223d
#   implications, but I need to decide what copyright information the
Alain Reguera Delgado 66223d
#   tcar.sh script will print out when someone request
Alain Reguera Delgado 66223d
#   information about it.  So, in that sake, I am using The CentOS
