Of course, you may unpack SAM and its libraries using any method that works, but I recommend using tar.

When using tar please heed the following:

• tar will make files with the original ownership when unpacking as super user (I will refer to super user as "root"), but will convert the ownership to that of the current user when unpacking as non-root.

  Therefore, you should know I intend that the successful use of SAM will not depend on the ownership of the files contained in it.  SAM should work fine whether unpacked using tar as root or as non-root.

• When unpacking as non-root tar will, by default, apply the user's umask when extracting permissions from the archive (also called a "tarball").

I recommend unpacking using tar as root, if you are able.
