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.
