un-tarring a disk file

[Devon Prichard]

summary says it all; I have a file (gnuplot.tar.Z from Duke Univ.)
which I want to bust out on a unix system.  I looked at the man
pages for tar, but it sort of implied it wanted a disk-to-tape
or tape-to-disk operation.  how do I untar a disk file and write
disk files??

thanx in advance
