+] 
+.SH DESCRIPTION
+.I Import
+allows an arbitrary
+.I file
+on a remote
+.I system
+to be imported into the local name space.
+Usually
+.I file
+is a directory, so the complete
+file tree under the directory is made available.
+.PP
+A process is started on the
+remote machine, with authority of the user of
+.IR import ,
+to perform work for the local machine using the
+.IR exportfs (4)
+service.
+If
+.I mountpoint
+is omitted
+.I import
+uses the name of the remote
+.I file
+as the local mount point.
+.PP
+If
+.I file
+is a directory,
+.I import
+allows options exactly as in
+.I mount
+and
+.IR bind (1)
+to control the construction of union directories.
+.PP
+The
+.B -E
+option causes
+.I import
+to push an authentication protocol on its network connection.
+Currently, the protocols supported are
+.B clear
+(the default) which pushes no protocol,
+and
+.BR ssl .
+There are plans to make
+.B tls
+available too.
+.PP
+The
+.B -e
+option specifies the encryption and authentication algorithms to use for
+encrypting the wire traffic.  The defaults are
+.B rc4_256
+and
+.BR sha1 .
+The full list of supported protocols in in
+.IR ssl (3).
+.PP
+The
+.B -p
+option pushes the
+.B aan
+filter onto the connection.  This filter will protect the connection from
+temporary network outages; see
+.IR aan (1).
+.PP
+The
+.B -s
+option posts the connection's mountable file descriptor in
+.B /srv
+under the given name.
+.SH EXAMPLE
+Assume a machine
+.B kremvax
+that has IP interfaces for the company intranet and the global
+internet mounted on
+.I /net
+and
+.I /net.alt
+respectively.
+Any machine inside the company can get telnet out to the global
+internet using:
+.IP
+.EX
+import -a kremvax /net.alt
+telnet /net.alt/tcp!ucbvax
