.SH WARNING
The renaming has no safeguards except the
.B \-\-no\-act
option.  If the user has
permission to rewrite file names, the command will perform the action without
any questions.  For example, the result can be quite drastic when the command
is run as root in the /lib directory.  Always make a backup before running the
command, unless you truly know what you are doing.
