+.SH DESCRIPTION
+.I Tarfs
+makes the contents of the directories and files archived in the given Unix/POSIX

+archive
+.I tarfile
+visible in the name space under
+.IR mountpt .
+They can then be accessed in an obvious way by other commands
+such as

+and

+Only read access is supported.
+User and group names are taken from the ``ustar'' headers when present.  Otherwise, the numeric user and group IDs are used.
+The

+and

+name space to be placed after or before the current contents of
+.IR mountpt ;
+the default is to replace that directory's contents.
+Option

+causes permissions in the tar file to be discarded.
