cd /usr
mkdir /opt
cd /
ln -s /usr/opt /opt

that's my solution to /opt.  (if /opt already exists, move it to /usr,
then do the ln -s)

tar    : you know this
c      : create
p      : preserve permisions (rwx and owners, etc)
f      : file name, the next arg will give the name of the file
-      : most commands understand this to mean stdin/stdout.
         tar is one, so this is stdout.
.      : the current directory.  if you make a tar file of
         . and then do a tar t of it, everything will look like
         ./foo, ./bar, ./zoo/cow, and so on.  an ls -a will show
         both . and .. dirs.

the parenthesis around the other two commands force them into a
subshell, so it's almost like piping into a shell script.  that way the
cd command takes effect, and that's also why the cd doesn't affect your
current session - at the end of this command you'll still be in /usr.
