+.TH EXPORT 4
+.SH NAME
+export \- export name space on a connection
+.SH SYNOPSIS
+.B export
+[
+.B \-a
+]
+.I dir
+[
+.I file
+]
+.SH DESCRIPTION
+.I Export
+calls
+.IR sys-export (2)
+to serve the name space rooted at
+.I dir
+over a connection to a 9P (Styx) client.
+.I Export
+opens the connection on the given
+.IR file ,
+or uses the standard input by default.
+It returns when the client closes the connection.
+If the
+.B \-a
+option is given, however,
+.I export
+starts an Inferno kernel process
+to serve the name space and returns immediately.
+.I Export
+serves the current name space without forking it; changes made to it
+will be visible to clients.
+.PP
+.I Export
+starts serving 9P immediately; it assumes that the connection
+has been authenticated if required.
+.I Export
+is typically called via
+.IR listen (1),
+which can authenticate the connection.
+.SH EXAMPLE
+Start a background process to serve the name space on the serial port.
+.IP
+.B "export / /dev/eia0 &"
+.PP
+Although useful when bootstrapping a system, this is unsafe
+unless a transport protocol is run on the connection.
