Notice to the user:

It is perfectly legal for this script to run without making any changes
to your system. This means that the system currently contains the
necessary changes to support this package. Please do not attempt to
force this script to replace any file nor make any patch. If you do so
then it is probable that you are actually putting older, buggier, code
over the newer, fixed, code. Thank you.
